Advertising interface route into different VRFs

bhaskar038
Level 1
Level 1

Hi,

 

I'm trying to configure VRFs for multiple providers and struck with the following. The router R1 is connected to Provider-1, Switch and Provider-2. BGP is running between provider and R1. 

 

Provider-1 is in VRF-1 and Provider-2 is in VRF-2. But, the f0/0 is in global routing table. I would like to advertise the f0/0 subnet to all the provider VRFs. I tried network XXXX mask xxxx. But, still not advertising as the subnet is not in routing table.Can someone help me this?

Weird.

ROM: 3700 Software (C3745-ADVIPSERVICESK9-M), Version 12.4(25d), RELEASE SOFTWARE (fc1)

Will try with different ios and let you know if it works,

Georg,

Tried with different router (CSR)Cisco IOS Software, CSR1000V Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.6(1)S, RELEASE SOFTWARE (fc4)

still does not work. Could you share your config?

Here is the config, identical to yours except for the interfaces used. I also posted the output of the routing table for both VRFs:

Thanks. Its getting really Weird. Its not working on same version as well.

Can you post the 'show version' of your router ?
