VRF-Lite on Cat6506

[pvezina]

Hello,

I'm trying to configure VRF-Lite on a cat6506, Native IOS. I can define the different VRFs, but when I try to put an interface into a VRF, the system tells me that VRF is not supported on that interface. I tried it on a physical layer-3 interface and also on a VLAN interface. Do I need special hardware or software on my 6506 to be able to use VRF-Lite? Right now I have a Sup2-MSFC2, and I'm running 12.1(23)E2 Enterprise. Thanks.

You need Sup720. VRF-Lite is not supported on Sup2/MSFC2.

Hi,

I actually have it working on a Sup1a/MSFC native IOS.

I had the same issue - it did not accept interfaces being put into the VRFs.

I found out that I needed to configure an RD under each VRF before I could put interfaces into them.

I did that - afterwards it worked both with physical and logical (VLAN) interfaces.

- Terribly sorry - I don't remember the exact IOS version, but I believe it was 12.1.something...

Cheers!

I configured an RD for the VRF, but I still can't assign the interface to the VRF. The exact message I'm getting is:

%This interface does not support ip vrf forwarding

Do you know if you had a special version of IOS? (like Service Provider)

Hi again,

The switch in my setup is running:

c6sup11-jk2sv-mz.121-22.E1.bin

Enterprise W/VIP SSH 3DES

Here is the VRF related config:
