Cisco WAN :: Multicast Routing Between Vrf (Cat 3750) - Multicast Vpn Extranet?
Feb 19, 2013
I try to pass multicast traffic between two vrf on the same 3750 switch. I have IP services IOS and sdm template routing.
here is my config:
ip routing
!
ip vrf vpn2
rd 1:1
mdt default 232.1.1.1
route-target export 1:1
route-target import 1:1
[code]....
Now I'm stuck - I don't know what to do to pass multicast traffic. Do I have any chance to run this config on 3750 chassis?Perhaps "Configuring Multicast VPN Extranet Support" document will be useful, but it concerns Catalyst 6500? [URL]

I have a subnet with a GPS clock on it that connects into a Cisco 3750. The 3750 has another subnet hanging off of it that connects into a firewall then to a server. I need the server to get time from the GPS clock. Any way to pass the NTP through the 3750? The 3750 has the 3750-IPBase code running on it so the multicast support is limited. I am under regulatory restrictions that only allow traffic to flow from the higher security level (were the time server is) to lower security level (were the server is). This prevents me from having the server go to the clock for updates.

I've been handed a requirement to try and get a multicast server working on my setup. Trouble is, I don't know if I can with the feature set I have on my switches. What is desired is that a multicast server (stand alone, but network connected, obviously) be accessible by everyone on the local network (multiple V LAN's, multiple SVI's) in the building.
All users will be connected to the one switch stack, although some will want to be wireless (which is one of the separate V LAN's) - I don't care if the wireless requirement goes by the wayside - they can sod off. :-) The main purpose will be multicast, high quality video.
I have a single switch stack consisting of two (soon to be 3) WS-C3750X-48P switches running the IP BASE feature set.
Question - can I do this on IP BASE, or do I need to upgrade to IP SERVICES?
If I can do it on IP BASE, does anyone have any links/pointers to setup this properly? Currently installed IOS is 12.2(58)SE2.

I have PC_A and PC_B connected to the same switch, and are put in the same vlan. PC_A is the master (source) and PC_B is the destination (client). IGMP Snooping is enabled by default.
Is there any reason why this should fail? There is no RP or any interface with PIM enabled. Its a flat network with a source and client in the same vlan...

A multisite network is currently supporting muticast using PIM dense mode, which is enabled on router/switch LAN and WAN interfaces across all locations. I am about to introduce Nexus switches to the main LAN. How can I make dense and sparse mode coexist to ensure flow of muticast traffic between devices supporting and dense and sparse mode? Eventually, I want to transition to the sparse mode; however, it has to be done gradually, even within a single site. The leacy equipment includes Cat 3750 and 4500s.

I have a LAN with multiple VLANs connected through Catalyst 3750 with IP Base image. In IP Base the router only supports PIM stub multicast (no PIM multicast routing),But I have an ASA connected to the internal router and to the internet router.Asa supports PIM multicast routing and can act as PIM RP. With this configuration, is there a way to configure an internal multicast network? That is a multicast server in one internal vlan (VLAN 1) and multicast clients in VLAN 2. Both VLANs connected to the C3750 router.

We are experiencing some issues with the Apple TV and WLC. We currently have a Apple TV and iPhone same sub net connecting via Lightweight AP (different sub net) which connects to a Cisco3750 running IP Base. This connects to WAN routers managed by third party over a WAN and connects to far end Managed routers, these connect to other Cisco3750 IP Base and onto a 2504 Wireless LAN controller. We have used the the following document for WLC configuration; [URL]
We turn on Multicast globally, with IGMP snooping enabled also enable Multicast Multicast under controller (only option available on 2504) and give the device M Cast address 239.21.1.150 . The P2P blocking action is disabled. Going to Monitor Multicast we can see the Report for 224.0.0.251 and MGID. However the issue is at the Sender Receiver side the iPhone cannot see the Airplay on the iPhone that should be seen if the end to end stream is working. My focus is now on the Cisco3750's, although I do not totally understand why the device needs Multicast enabled as the Multicast Join and Group Traffic is encapsulated in the CAP WAP Tunnel is it not? Anyway I have enabled the only option "ip multicast routing distributed" and under the V LANs that connect to WLC and AP the only option available is the "ip pim passive" there is no "ip pim sparese-dense mode"
I am sure the WLC is configured correctly, but I suspect that this will not work due to the IP Base image on the 3750's not being able to run full multicast or we need to use uni cast for this solution that the 2504 does not support.

I have multicast routing setup between two Nexus 7K's.These Nexus 7K's act as the distribution layer and they connect to 48 different 4507 access layer switches (VPC) and 3 6509 core layer switches.The 4507 swiches have two supervisor modules. One acting as active and the other as hot standby. Let's assume that multicast is working on the active module. If I pull out the active module the hot standby takes it's place. This is where multicast stops working on the switch.How can I get both Nexus 7K's to work with multicast at the same time. Here is an example of show ip mroute from both Nexus 7K's:note that DR02 has a lot more entries in the routing table. Is this working as designed?

I have a application whose components are talking to each other via one multicast address 235.19.4.10.
This application is running on two different IP Subnets 192.168.121.0/24 and 192.168.99.0/24. It must be required that these two IP Subnets must not see each other thus they are configured on two different VLANs. Now we have a requirement where this application need to be installed on Remote Sites where Routers will be used to provide the connectivity.
The problem I am facing is that if I will configure the Remote Sites with some other IP Subnets e.g. 192.168.1.0/24 than Networks are unable to talk to each other even Multicast Routing is configured on Routers. Now at least as per my requirement, I need two separate subnets need to be configured on remote sites where one subnet will communicate with Subnet 192.168.121.0/24 and other subnet will communicate with 192.168.99.0/24.

I am IT teacher at a middle school in Nuremberg, Germany. We have in our school 5 VLANs, 4 Switchtes, 1 L3 switch and 1 router.
2 months ago the old L3 switch (Catalyst 3550-12T) is broken. In the short term I've borrowed a Catalyst 3750G-24, so that the network continues to function. Now a SG 300-10 switch was purchased. This should be configured the same as the 3550-12T or 3750-24G.The network looks like this (there are much more PCS than in this image):
VLAN ID
VLAN Interface
DHCP
DHCP-pool
[Code]....
The DHCP server in VLAN 30 is also a FOG server. The Fog server images all PCs in school. PCs in VLAN 10, 20 and 30 boot from PXE. The MS Server in VLAN 10 has been configured by the DHCP options 66 and 67.
The Catalyst 3750G-24 routes the multicast, but the SG 300-10 I do not have the option of using the commands ip multicast-routing distributedip pim sparse-dense-modeto work and must configure igmp. I'm having problems with the igmp-configuration on the SG 300-10. Therefore, I have uploaded the configuration of the 3750G-24 and the configuration of the SG 300-10 (without ACL).

I'm trying to configure multicast between 2 VLANs on a Cisco 886VA running IOS 15.2 (3) T1 (advanced security). While I can set the global "ip multicast-routing" I cannot "ip pim sparse-mode" on my interfaces - ip pim is actually unknown and also doesn't appear in the interface's ip subcommand list when using "?".
The feature navigator says pim is supported on my platform and IOS version.
My config looks like this:
interface FastEthernet3
switchport access vlan 103
no ip address

I recently created a stack using (2) 3750x switches. I have three vlans on the stack (1,105,241) Vlan 105 is configured on 6509 core switches with multicasting and are connected to the stack via gigabit fiber. It is working well with clients on the Master or SW1, however clients on SW2 do not participate in multicasting Any client pc that is connected to SW2 vlan 105 does not show up in the "sh ip igmp snooping group" command. I can statically assign a client on SW2 to the mcast groups but but they fail to register on their own. I can take the cable connection from SW2 and plug it into an SW1 Vlan 105 port and it immediately becomes a member of the groups. I can then connect it back to the SW2 port and it disappears from the group membership. IGMP and PIM are configured with the defaults.

I have a 3560X switch with interfaces 36-48 on the same LAN. All interfaces are switchports. Hosts on 38, 39 and 40 are multicast senders: all sending to the same single multicast address. Hosts on 36 and 37 are receivers, having joined that multicast group. I created an SVI for the LAN and put it in ip pim passive. (That is the only PIM mode allowed for an SVI with my IOS.) Show ip igmp snooping groups shows that 36 and 37 are the only interfaces in this group. I attach a laptop to interface 42 and Wireshark, and the laptop is receiving the multicast traffic. The laptop does not join the group. I expect it would not see the traffic.

We have an ASA-5540 (8.4(1)) The inside interface faces a few multicast receivers. The outside interface faces the multicast source.All of the ASA multicast documents I've download describe very simple network designs, such as a single segment on the ASA inside.Our PC hosts that will be multicast receivers are a couple router hops away from the ASA inside interface. I'm not sure what the best way is to configure multicast on the ASA.Should I configure the ASA with PIM routing and a static RP address (plus the ACL to allow the multicast source traffic in) since the receiver hosts are a couple hops away? I think I understand the IGMP joins are for a local PIM router, so configuring as a Stub Multicast router wouldn't work? The two Cisco routers between the host and the inside ASA interface already have PIM, a static RP address, and IP PIM Spare-Mode configured.

I have the need to filter multicast between vlans as described below. PIM Sparse-Mode is being utilized for this multicast network and changing any Vlan to PIM Dense mode is not an option.
- Vlan 217 and Vlan 4 should not be communicating on mcast with any other vlan, including eachother (each vlan isolated).
-Vlan 64 and Vlan 80 are able to communicate witch each other on mcast but not with any other vlans (isolated vlan group).
-All other vlans can communicate mcast freely.
What I've created thus far is below. It does not appear to be the most elegant solution and would be difficult for the administrators to adjust as new requirements come along. Yes, I will be adding the appropriate link-local multicast addresses so as to not break routing and other dependent technologies.
ip access-list ext ANY_CONN
permit ip any any
ip access-list ext MCAST_INTRA_217
permit ip 224.0.0.0 15.255.255.255 133.106.197.32 255.255.224.0
permit ip 133.106.197.32 255.255.224.0 224.0.0.0 15.255.255.255
ip access-list ext MCAST_ISOLATE

pinging the SVI on the core and or pinging on the core to other devices resulted in MAJOR latencies, packet loss due to the cpu usage, etc.... no other network operations were affected, i could communicate with the rest of the network, and under 1-2ms latencies. i noticed it due to my opsview server flagging the core as down (SNMP OID's wouldnt return a value)
it lasted the whole time i was multicasting, i kept a close eye on it. i highly considered canceling my job, but everything ran smooth.when i looked at the cpu sorted history i saw 2 processes, IP Input, and cat4k mgmnt hipri

A brief background on the setup: I recently switched out my switch. It was a Cisco 3750 10/100 switch and I wanted to upgrade to Gig. The cost of a Gig+POE 3750 is too much to bite so I opted for the SG300. My router is a Cisco 891. Here is the setup:
Cisco 891:
two SVI's: vlan1 and vlan 100
Vlan1 = 10.0.1.1/24
[Code].....
With the 891+3750, I was able to add "ip pim sparse-dense-mode" on all the SVI's and hosts could join any multicast group, irregardless of which vlan the host was a member of.
Now I've changed switches, and I dont get the same love. I have the PIM statement on both SVI's on the 891, but Im unsure of what I need to configure on the SG300. I have enabled "Bridge multicast filtering" + "IGMP snooping". What can I do to get similar functionality using the SG300 + 891? I assume this is my lack of understanding IGMP in general, but was able to get away with it using the PIM statements on the 891+3750 stack.

I start configuring Cisco 2821 router for multicast . First short description and attached sheme explanation. Let we say I have small network with 100 users. One router and Cisco switch 3560. Two VLAN’s, one for data another for multicast. Data from internet works fine but now I want to connect multicast servers (or source of more multicast streams) from another subnet. Router have three interfaces.I expect there should be no problems with multicast configuration, but unfortunately it is not like I expect. What I did ?
First step: enable multicast routing
Second step: on both interfaces (Fe 0/1 and Fe 0/2) - ip pim sparse-mode
Third step: configure switch that users are connected to access port in VLAN 222 (temporary to see if multicast work)
When I start VLC on computer nothing happend. If I try to connect computer on same subnet where is source of multicast streams it works fine.What I am doing wrong ? Is there anything about routing ? All subnets are directly connected. RP is not needed if I have one router or ?

I have a problem on my catalyst 6509 on which I would like to do the following things :
I have some Vlans in which multicast is enabled.
In tose Vlan theres is a router which is default router for equipements.
I had enabled multicast routing because some Vlan needs to exchange multicast informations, but I wolud like to make difference between Multicast traffic. For example I have 5 vlans:
Vlan 1 and 2 need to exchange Multicast informations but the don't need multicast information from Vlan 3 and 4
Vlan 3 and 5 need to exchange Multicast informations but the don't need multicast information from Vlan 1 and 2
Vlan 5 is independant Vlan but doesn't need to have multicast information from all others vlan.
Last problem, equipement on differents vlan can use the same Mulkticast group address. In this case, Multicast routing is not working between Vlan 1 to Vlan 2 and Vlan 3 to Vlan 4.

I am configuring multicast in a environment where I have a 4506 at each site (4 total) and a 6506 as the core. Each 4506 is connected via layer 3 to the 6506. I have a mix of 3560s, 3548s, and 2960s connected to the 4506s and the 6506 via layer 2 trunk
I have multiple multicast sources and hosts communicating at a time (multiple cameras sending video / multiple computers receiving video). So this is not a scenario where there is 1 sender and many receivers. This would be many senders (~50) and some receivers (~10)
Sample Diagram:
->3560
|
6506 --> 4506 --> 3548
| |
| --> 2960
|
4506 --> 2960
|
-->3548
I configured ip multicast-routing on each of the 4506s and on the 6506. IGMP snooping is on by default on the 3560 and 2960 switches. CGMP is on by default on the 3548 switches.
I set up PIM sparse-dense mode and IGMP version 3 on each of the layer 3 interfaces for the 4506s and 6506 where they connect and on each VLAN that is sending or receiving multicast. Multicast is working throughout the network, however I am looking to verify the configuration as I scale this out to more clients on the network.
#1 - Is it correct to us sparse-dense mode in this configuration?
#2 - Do I need to configure a rendezvous points using AUTO-RP? (ip pim send-rp-announce INTERFACE scope TTL). Not sure here if I need to designate this and what to choose. Right now I do not have this and it is working, but documentation seems to infer that I need to designate this.
#3 - Is there any other configuration settings I should be considering? I hard to find real world configurations of multicast as examples or people that know multicast routing well.

I would like test multicast routing with cisco1801.i create 2 Vlan. Vlan 200 (192.168.200.x) affect Fastethernet 1, Vlan 130 (192.168.130.x) Fastethernet 5.
Version IOS is : adipservice-k9 124-9.t1
ip multicast-routing
#int Vlan 130
ip address 192.168.130.254 255.255.255.0
Ip pim dense-mode
#int Vlan 200
Ip address 192.168.200.254 255.255.255.0
Ip pim dense-mode
I used VLC for my test.When i connect source (224.10.10.10) and recever ( Udp://@224.10.10.10:1234), that's ok!But, source is on the Vlan 200 and reicever on the Vlan 130, is not good!I test with "sparse-mode", i have same problem.

I have a 2960G that I keep on the bench as a work switch. I assigned an IP address to it. The techs have had trouble imaging workstations using GHOST. Do any config changes need to be made to enable multicast to work? Everything is in VLAN1 at this point and the GHOST server is also the DHCP server.

I can't seem to find where in ASDM (6.4.1), can we configure IGMP forwarding? ASA5520(config-if)# igmp forward interface outside The ASDM doc reference does not seem to be correct pointing to:configuring Stub Multicast Routing
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > Multicast > IGMP.

We have a couple of switches with a L3 Vlan 238 interface which runs PIM SM and OSPF, and HSRP. We have connected to this same segment telemetry processors which have raw socket interfaces configured - which means it picks up all IP packets which hit the interface and forwards them along.So we dont want the processor to recevie any of the 224.x.x.x switch housekeeping traffic? is there anyway to prevent that ?

The two servers (red hat) use multicast for their heartbeat. Unrouted vlan 99 (only layer 2) is configured on the VTP Servers (6509).I have read this document [URL]
Switches 1 and 2 have IOS: c2960s-universalk9-mz.122-55.SE3.bin
and the 6509: s72033-advipservicesk9_wan-mz.122-18.SXF17a.bin
IGMP snooping is enabled on the 2960 switches.In order for the heartbeat of the servers to work, I have tried these solutions:disable igmp snooping for vlan 99 on switch-1 & switch-2. (No additional action was taken on the 6509). This didn't work. I expected that the multicast traffic would be sent as broadcast throughout the network, but for some reason it didn't work.on switch-1 & switch-2 configured "ip igmp snooping vlan 99 querier" (no additional actions on 6509). Didn't work either.on switch-1 & switch-2 configured "ip igmp snooping vlan 99 mrouter interface gigabitEthernet 1/0/25" & "ip igmp snooping vlan 99 mrouter interface gigabitEthernet 1/0/26" for the two connections to the 6509. Again no actions taken on 6509. Didn't work. I want static mac entries on the switches to be my last resort, since the number of red hat servers on the network is going to increase and I want to give a more generic solution to the issue.
