Does IOS XR support vrf lite?

[aacole]

Am researching PE-CE configuration for a multiservice CE, using eBGP as the protocol. The XR fundermentals book describes this, but does not give an example of the CE configuration.

I want to configure several sub-interfaces and alloacate to different VRF's, running vrf lite on CE. The sub-interface bit works fine. I cannot find which document describes vrf lite configuration, am using XR 4.3.0.

does anyone have an example of how to set up an IOS XR ce with vrf lite they could share, using ebgp as the routing protocol?

Hi,

config will be pretty straightforward:

- define the VRF (no need to asign it any RD/RT, just an address-family)

- assign interfaces to it

Ex:

vrf Test

address-family ipv4 unicast

!

interface Te0/0/0/0

description Test

vrf Test

ipv4 address 192.168.1.1 255.255.255.0

load-interval 30

!

Shouldn't be more complex than that,

cheers,

N.

ok, I see that bit. So I set this up with sub-interfaces, assign each to a vrf. Works great!

How do configure eBGP to act as the PE-CE routing protocol, it is that bit that I cannot get to work. I configured BGP, defined the vrf's under the BGP process, and then defined the neighbors under the BGP/VRF settings. The eBGP peerings all established, but no prefixes were received. And yes, I had an inbound/outbound route policy configured.

will have another look later today at this, but any suggestions greatfully received.

If you could paste a sanitized config that would probably help.
