VRF configuration on IOS-XR 4.1.

Hi

I have some questions about VRF configuration on IOS-XR 4.1.

I'm trying to configure BGP routing with vrf and I get the

following error when trying to commit my config:

===================================================

address-family ipv4 unicast

!!% 'BGP' detected the 'warning' condition 'The parent address family

has not been initialized'

===================================================

However, It is solved by configure "address-family vpnv4 unicast"

before committing the vrfs.

But, I'm not sure about that above configure are best practice or not.

Q1. Do you have a best practice configuration of BGP with VRF?

or

Q2. I have to use "address-family vpnv4 unicast" on IOS-XR ?

Please advice me.

Best regards,

Kim

Hi Kim ,

you must configure "address-family vpnv4 unicast" on BGP globally so you will be able to commit the configuration for the address-family.


You can refer the below link to understand how MPLS L3VPN's are configured on IOS-Xr.
