Cisco Switching/Routing :: 2821 And 3560 Multicast Servers Connection
May 9, 2012
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 ?

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.

We have a server connected to a 3560 switch which in turn connects to 6500s. The gateway interface is on the 6500. We will be changing the 6500s so the mac address for the gateway will change, however the IP address will remain the same. As we change out the 6500s the uplink connections to the 3560 will go down. This will flush the old mac address from the 3560.When the 3560 removes a MAC address does it update servers so they have to relearn the correct MAC address?

I have 5 linux and 3 Microsoft 2008 Servers, each connected to 2 Cisco 3560 Switches. The 2 Cisco 3560 switches are connected to 2 different Cisco 515e Pix. Is it possible that if i enable Port SPAN in any of the switchport and send a copy of traffic to any of the windows 2008 server, will i be able to monitor the bandwidth of the servers (Here I am only looking for traffic going from servers to PIX and then to internet, also vice versa).
Also will wireshark be able to differentiate specify the bandwidth of each servers seperately ?

I have two 3560s that i would like to upgrade. But first i would like to make -absolutely- sure i dont wind up in a situation where i have to roll back over a console connection.to the day i still cant understand why oh why someone removed (or chose not to implement it everywhere) tftpdnld from rommon ;)

For some special arrangement, I would like to connect 2 access ports from a 3550 switch to 3560 switch.1 port for vlan 200, another port for vlan 201.Will this introduce bad thing to the switches?

i am not sure if this is something with my DHCP setup or not, but it certainly seems to be the culprit. I am running a 3560G and using it as DHCP and to do V LAN routing (Geiger protocol). I have 10 pools configured with a few static addresses per pool. Now to get down to the problem. I have a computer (and this problem seems to be a gremlin as it changes what computer is affected quite often) that will connect, get its IP, immediately disconnect, then send out a DHCP req again. The computer has a static assignment in the pool, and for the brief second that it connects, it gets the right address. If i move the computer to another v lan, all works right. If i delete the static entry it will get an address in the right v lan no problem. The command i have been using to add static entries is:
address xxx.xxx.xxx.xxx client-id 01xx.xxxx.xxxx.xx
That seems to have been working on all my static routes except for a bank of computers in vlan3. I have went as far as to delete the pool and recreate it, heck i even recreated the v lan and i am still having issues. Below are some snippets of the running config for review.
The DHCP Pool for the affected LAN:
ip dhcp pool Dev3
network 192.168.3.0 255.255.255.0
boot file bootx86wdsnbp.com
next-server 192.168.1.78
dns- server 192.168.1.8 192.168.1.78

I have been reading for awhile now on all the Cisco forums on the 3560 and shaping egress traffic but I wanted to verify my thoughts on this. I have 3560 that connects to the ISP that is policing at 10Megs, I want to shape my egress traffic going to the ISP, I do not want to provided QOS to any specific traffic type but only shape all traffic outbound. Will my config below shape "all" egress traffic going to the ISP on the 3560, on a port that is physically connect at 100Meg Full duplex?
int gi0/1
srr-queue bandwidth shape 40 40 40 40
I gathered these numbers using the formula of 100* 1/weight, which would equal 2.5 and if each queue has 2.5 meg that would = 10Meg. However another concern is that I don't think I have the full 100Meg on the interface to use (correct?)

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]

Ihave a 3560 w/multicast support and I'm trying to configure a simple environment. I have 2 ports configured, one for the multicast server and the other for the client. Each are on their own subnet, so I have an ip route between the two. My run config on both ports is:
ip multicast-routing distributed
interface fastethernet 0/3 & 0/4
ip pim version 2
ip pim sparse-dense-mode
I'm using vlc server /client configured to use 224.0.0.1 on my isolated network. I can see the mulitcast traffic going into the port, and I the client is sending reports, but I think the 3560 is dropping the packets, since I don't see them coming in the client port. Need to configure a simple multicast environment using 2 ports on a Cisco 3560.

We've got a cisco 2821 router which periodically stops routing all traffic. It seems to happen about once every 2 weeks, and I can't find anything that could be causing it. There are no entries in the log and the router stays up and running but requires a restart to begin processing traffic again. We're running 12.4(13r)T11.Any thoughts, or troubleshooting steps to track this down?

I have just bought myself a Cisco 2821 ISR.At present in my home I have a Cisco 2621XM. Fast Ethernet 0/0 is connected to a 3524XL as a trunk to provide my LAN with inter-vlan routing. it works great. Fast Ethernet 0/1 is connected to my ISP's cable modem and uses the command "Ip address dhcp" to get an IP and all other info from my ISP.FA 0/1 is Ip nat outside and the FA 0/0 and all sub interface like 0/0.1 .24 .168 etc all ip nat inside.I get intervlan routing and access to the internet via this router.I have this 2821 to replace the 2621XM as I plan to run CME on it and want gigabit routing on my vlans as at the moment on the 2621 routing between vlans it at half duplex or seems to be.I have configured the 2821 to ip nat outside on gig 0/0 and ip nat inside on gig 0/1 and all of the sub interfaces (same setup as my 2621 but with gig ethernet)I have no access to the internet at all but I can ping www.google.co.uk and other domain names from the terminal session when I am connected to the 2821 via the console or telnet/SSH. the gig 0/0 has an IP assigned from my ISP too but no other nodes on the network can ping outside.Am I missing something here? the version of IOS is V 15.
My access list goes someting like
access-list 1 permit 10.0.0.0 0.255.255.255
access-list 1 permit 192.168.1.0 0.0.0.255
access-list 100 permit ip 10.0.0.0 0.255.255.255 any
access-list 100 permit ip 192.168.1.0 0.0.0.255 any
and so on
I still cannot access the internet.....

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 Cisco 2821 Router. Its ethernet Interface(E1) is connected to an ISP's Gateway.The outside interface IP is 207.x.x.1, The ISP has given 6 public IPs (202.x.x.1- 202.x.x.6) to use in LAN.
I have configured the router`s Internal Interface(E0) with a public IP address. (i.e. 202.x.x.1)
My Internal LAN PCs are in a private range of 192.168.1.0/24 subnet. Now I wanted my PC users to access the Internet while the Routers public IP remains on internal interface. How can I do the same?

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 have a 5412zl 10.215.x.x/16 Most of the connections on this switch are on vlan1. B9 is the port which is connected to a Cisco 2821 Router. The port on that end is GE0/1. The port on the cisco side is not a trunk but configure with an ip of 10.215.1.30/24 Its part of a some ip access group. The network that i now sit on is a 172.x.x.x/24 (behind cisco router, about 3 hops to that main 2821)We current have a system on my side that talks to a server on the 10.215. that has no issues. I'm trying to access some switches on the 10.215. and have had no luck reaching them.
Here is the access list that i found that port is configured to use:
permit ip 10.215.0.0 0.0.255.255 172.18.0.0 0.0.255.255 permit ip 10.254.0.0 0.0.255.255 172.18.0.0 0.0.255.255 permit ip 10.215.0.0 0.0.255.255 172.14.0.0 0.0.255.255 permit ip 10.254.0.0 0.0.255.255 172.14.0.0 0.0.255.255 permit ip 10.215.0.0 0.0.255.255 192.168.2.0 0.0.0.255 permit ip 10.254.0.0 0.0.255.255 192.168.2.0 0.0.0.255 permit ip 10.215.0.0 0.0.255.255 192.168.20.0 0.0.0.255 permit ip 10.254.0.0 0.0.255.255 192.168.20.0 0.0.0.255 I would think the first permit would allow me to get through to the 10.215 side but maybe i need to set something up on the hp size to let it know how to get back? I'm very new to this stuff.

| |
EIGRP EIGRP

2821 -----------MPLS----------1841
BGP
The MPLS connection is currently down, I'm trying to run a failover Site-to-Site VPN over the internet. All of the examples I've read have both connections involved in the failover coming out of one device. Since I'm not working that way, what is going to be the best way to failover? Do I need to set up some sort of IP SLA in the config? Or can I somehow weight routes in EIGRP in a way that the connection will failover from Internet to MPLS when the MPLS goes down and vice versa when the MPLS connection comes back up?

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.

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
