ASR9000 with IOS XE - No inter vrf routing ?

[joyride_us2]

Hi,

I am trying to find a way to perform inter-vrf routing for a given prefix....on an ASR9000 with IOS XE.

Any solution ?

Hi

You want to leak route from 1 vrf to another vrf or from 1 vrf to global?
Are you already using a dynamic routing protocol?
Can you share your config (routing and vrf) + tell what prefix you want to leak?
I'll do the config for you to show you how to do so.

Hello Joy!

Did you review this post? Jain do that in a ASK1000 https://supportforums.cisco.com/t5/service-providers-blogs/inter-vrf-routing/ba-p/3102707

Hi Diana

I was talking about inter-vrf routing on the 1 router : you come in the router through a VRF and go out another one if you target that prefix.

thanks!

Could you please specify if you are looking for a solution for the ASR9000, which runs IOS XR, or for another platform running IOS XE. The title is conflicting.

Hi Harold!

Cisco ASR9K Series is the platform. And Cisco IOS XR Software is the firmware (sorry).

...and I cannot find a route-map command available! :)

Sorry for my late answer.

I would recommend to do it using BGP locally on the switch to leak routes from each vrf.

here a config sample: 

Let's assume you have vrf A and B with subnet 192.168.10.0/24 in vrf A and 192.168.20.0/24 in vrf B.

BGP config:

router bgp AS_number
bgp router-id x.x.x.x
address-family ipv4 unicast
!
address-family vpnv4 unicast
!
vrf A
rd 1:1
address-family ipv4 unicast
redistribute connected

vrf B
rd 2:2
address-family ipv4 unicast
redistribute connected

VRF config:

vrf A
address-family ipv4 unicast
import route-policy VRFB_2_VRFA
import route-target
1:1
2:2
!
export route-target
1:1
!
vrf B
address-family ipv4 unicast
import route-policy VRFA_2_VRFB
import route-target
1:1
2:2
!
export route-target
2:2

Route-Policy config:

route-policy VRFA_2_VRFB
if destination in (192.168.10.0/24) then
done
endif
end-policy

route-policy VRFB_2_VRFA
if destination in (192.168.20.0/24) then
done
endif
end-policy

Hope that helps
