Hi Aaron,
If you're doing this in the context of a BGP/MPLS VPN, then you already
have BGP in the picture and I think it would be better/simpler to use an
import or export map as others have suggested.
FWIW, replicated routes can be redistributed by IGPs (but not BGP) by
using a command like:
redistribute vrf red ...

Paul

thanks, per the config guidance below, I have that route replicated into the
vrf that I wanted it into on the local pe where I did that replicate trick
from one vrf to another.... but how would I get that replicated route sent
to other neighboring pe's in that L3VPN ?

Hi Aaron,
If you have a recent IOS release you can use the "route-replicate"
command to do this directly without requiring BGP. For example:
vrf definition blue
!
address-family ipv4
route-replicate from vrf red unicast all route-map red2blue
exit-address-family
!
vrf definition red
!
address-family ipv4
exit-address-family
!
ip prefix-list red2blue seq 5 permit 90.0.0.0/8 le 32 ip prefix-list
red2blue seq 10 permit 91.0.0.0/8 le 32 !
route-map red2blue permit 10
match ip address prefix-list red2blue
!
R1#sh ip ro vrf red

This is documented as part of the "Easy Virtual Network" feature, but can be
used by itself. See, for example:

ing_Easy_Virtual_Network_Shared_Services.html

if you have links to docs or sites that explain this or you know how ,
lemme know please.
