Can any share some useful links on how this works and how to configure it? Do you still need to configure FHRP or does configuring redundancy take care of active/standby relationship between the ASR's?

View 2 Replies View RelatedCurrently we have two inter-chassis FWSM redundancy. I would like to configure them for intra-chassis.
Both FWSM's are in slot 7 of 6509 switches and i want to take secondary out from one of the 6509 switch and insert in the slot 3 of primary switch.
I addedd the following commands in my primary switch.
There were commands already present for FWSM in primary switch
firewall multiple-vlan-interfaces
firewall module 7 vlan-group 1
firewall vlan-group 1 2,3,777
to create intra-chassis redundancy i addedd the following command also there.
firewall module 3 vlan-group 1
after adding that, my firewalls worked fine but there was a issue with site loading. People from outside were able to access inside but from inside, we were not able to go outside.
do we need to clear arp from both FWSM's ? is there any other precautionary step, which we need to follow while working on it.
I need to know, can i create svi on the ASR 1002 ?

View 1 Replies View Relatedwe are replacing network equipment at one of our sites. The network will have 12, 3750X switches(6 stacks) - one stack will be the core. A 1002 will be the WAN router to the Main campus. The 1002 will connect to the core via 2 ethernet cables. I'm debating whether to use L3 or L2 between the router and Core. I've heard that routing is more efficient if L3 is used and also I will be able to create an L3 etherchannel between the 1002 and Core switch. See the attached doc.

Some times perticular VLAN user will not be able to access the network but from the same switch others VLAN users can able to access. We were getting ARP entries in router but we cannot ping the IP's. Even we clear the ARP entries. Once we restart the switch users can access the network. We have changed vlan ports, uplink too. but problem not solved. and we observed CPU utilization will be going 70-80% some times and at same time switch hangs.

There is nothing in the config to cause this (it was actually pulled off a working production ASR 1002) and I am unable to ping a local loop back IP while consoled into the router?? I removed the config, reloaded the router and configured a new loop back - same issue cannot ping the loop back or anything else connected to this router.

We were going to create a 2 port, layer 3 etherchannel between a 1002 router and a 3750X layer 3 core switch. We wanted to create bunled link between them but, now we are going to be putting a Riverbed device between the router and core switch. Because of this, would it be best to abandon the idea of creating a layer 3 etherchannel and just have 2 links from the router and core switch and have traffic load balance between the 2 links?The Riverbed will have 2 connections into it from the Core switch and 2 connections into it from the 1002 router. I was hoping to keep the layer 3 etherchannel but, do you think it would be best to create 2, /29 nets and have the router/Riverbed and Core Switch/Riverbed load balance.

View 2 Replies View RelatedWe are preparing to install a new switching Infrastructure at one of our sites. We have decided that we want to have two separate chassis as a core. My original idea was to purchase 2 - 4500 chassis and install 10Gb and 1GB line cards in each and use STP and HSRP to load balance between the two cores.
We had also contacted a vendor for thier recommendations and they came back with 2 6500 Chassis running VSS. I reviewed what VSS was as I had never heard of it and it looks to me basically to be real close to the same thing as Stacking. I didn't really want to have stacked Cores because I would like to have the flexibility to be able to take one core out and update the software or image, reboot, and such without effecting anything on the network. I can do that with the non-VSS approach but it looks like that would be more of a problem with VSS.
My question is, how to use VSS with the 6500's? How to take one of the VSS pairs off line and not effect normal network operations?

View 12 Replies View RelatedI have a DC topology based on 2 layers, access and aggregation, based on 2 pairs of N5548Ps, both without L3 Daugher Cards. My intent is to use the aggregation N5K pair as L3 inter VLAN layer, so I configured all the VLAN default GWs there. The 2 layers are interconnected via vPC, in a double-sided vPC topology for some N2Ks and some vSwitches. The point is that, despite connecitivity is working fairly ok, for some applications, like file transfer via either FTP or HTTP, between hosts in different VLANs, the performance is too poor. The file transfer starts ok, but after a while it becomes lower and lower. ICMP is working, but I can see some strange random behaviour, like having some packets taking more that 20 ms (sometimes 40 or more), whilst average is 2 ms.
I read through some articles saying that until you don´t have the L3 license (the one coming with L3 Daughter Cards) you can expect some weird behaviour on L3 level. Is that true?. What can I do apart of purchasing L3 Daughter Cards?. Can I enable L3 Basic license at the moment (I don´t need dynamic routing for now).
Here some excerpts of what I´m saying:
PING results:

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]
We have two Cisco 5505 firewalls connecting to two ISP's . The two internal LAN's on the firewalls are 192.168.184.0/24 & 192.168.186.0/24. We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .
Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]
Can nexus 5010 supports inter v lan routing , as there is no core switch and router available in current network.

I am working for a large campus network. The network has more than 70 VLANS in a Layer 3 Switch(Catalyst 4503). Customer wants to stop intervlan routing between all vlans except 2 vlans. How will i do that? I have also a Firewall (ASA 5520) & a Router (2811) in up of the switch. Besides this, I have run HSRP in Layer 3 Switches for redundancy.how will i stop intervlan routing between VLANS except 2, with ACL or any other process has?
View 10 Replies View RelatedI'm looking to restrict Inter-VLAN routing through L3 switch (cisco 6500) and wanted to know best possible way to do it. I used VACL and achieved success to some extent, but my config is making clients take up to 5-6 mins to authenticate IP address from the DNS (bootps).My VACL config was as follows:
Subnet to restrict is 10.100.15.0 (VLAN 15)
STEP 1: Created extended ACL to allow bootpc/bootps through DNS
ip access-list extended EACL_DNS
permit udp any eq bootps any
permit udp any eq bootpc any
STEP 2: Created standard ACLs to allow only relevant subnet, server VLANs & some IPs from other subnets for printers/scanners etc.
ip access-list standard SACL_VLAN_15
permit 10.100.15.0 0.0.0.255 (the subnet I'm restricting)
permit 10.100.50.0 0.0.0.255 (server VLANs)
permit 10.100.25.45 0.0.0.0 (printer in another VLAN which has to have access in VLAN 15)
STEP 3: Created VLAN access list
vlan access-map VACL_15 10
match ip address EACL_DNS
action forward
vlan access-map VACL_15 20
match ip address SACL_15
action forward
STEP 4: Applying VLAN Access list on VLAN 15 vlan filter VACL_15 vlan-list 15 Though the above works, below is noted:
1. I'm still able to PING 10.100.15.2 (the switch virtual interface) from outside the subnet, which I don't intend to do so. Howeve all cients in the subnet have no connectivity from outside the VLAN 15.
2. As mentioned its taking quiet some time to negotiate with the DNS server at system boot time.
you find attached my network architecture with 2 Nexus 7010 on core layer and 2 Nexus 5020 on distribution layer, each one with 1 N2148T fabric extender switch. PC-A1 and PC-A2 are connected to one N2148T, PC-B1 is connected to the other N2148T. Nexus-7000-1 is HSRP Active for all VLANs, Nexus-7000-2 is HSRP standby. PC-A1 and PC-A2 are connected to VLAN A, PC-B1 is connected to VLAN B. PC-A1 and PC-A2 have the same default gateway correspondent to IP HSRP on VLAN A. It happens that PC-A1 is able to ping PC-B1 while PC-A2 is unable to ping PC-B1. If I issue a traceroute from PC-A2 I see Nexus-7000-2’s physical IP address as the first hop even if Nexus-7000-2 is HSRP standby. After the first hop the traceroute is lost. If I shutdown Port-channel 20 on Nexus-5000-2, PC-A2 starts to ping PC-B1.I can’t understand what’s wrong in this architecture.
View 6 Replies View RelatedI 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 SG 300-28 switch with the latest firmware installed running in Layer 3 mode.
I configured this router with 4 VLAN's where VLAN 1 is connected to the network router. All VLAN's call all communitcate with one another. How do I go about configuring VLAN's so that they can only communicate with the router and the internet and not each other?
I have one cisco 3750G-48 switch, one cisco 3560G-PS switch, Cisco UC520, cisco 2851 and cisco wireless access point.i have setup up intervlan routing between the two cisco switches and the uc520 with a total of four VLANS, the problem i'm having is with the 2851 router, I have created a trunk between the 3750 switch and the 2851 router. should I create subinterfaces on the 2851 router for the four vlans by doing gigabieethernet 0/0.1, 0/0.100 and so on or should I create BVI subinterfaces.
reason I ask is I created four vlans on the vtp server switch which is the 3750 and I connected the uc520 to the 3750 switch via a trunk interface and set up vtp client on the uc520, after I setup p the vtp on the uc520 the vlans were automatically created on the uc520 with each vlan having its own BVI interface.
So I am not sure how to configure the 2851 router to interact with the four vlans. also the 2851 router have two hwic 1adsl wics installed which will have two adsl connections coming in.how to set up the 2851.
I am looking for a reasonable switch but it has do do inter-VLAN Routing. I know I could go with a 3560/3750 with IP Services but I am also thinking the 2960S with IP Base IOS might do?
I have looked up the IP Base IOS and it does list IP Routing but how to actually configure inter-VLAN Routing on a 2960S with IP Base?
Every one i want to know ws-c4503E series 3 -slot chassis . I have compatibility issues with MEM-C4K-FLD64M AND S45EIPBK9-12240SG will work.
