Hi all,

I have a senario where I import routes fra VRF-A (RT 65002:4021) into VRF-B (RT 65001:1200).

I now would like to import the same routes (the ones imported from VRF-A) from VRF-B (RT 65001:1200) to VRF-C (RT 65002:1000).

Can this be done? If yes, how?

Hello ArnStran,

the correct way to do this is to export from source VRF VRF-A with both RT set

for example using a route-map as export-map

route-map myexport permit 10

match ....

set extcommunity RT 65001:1200 65002:1000 additive

ip vrf VRF-A

export-map myexport

you cannot re-export from VRFB to VRFC to avoid possible routing loops

Hope to help
