Re: Redistribution between VRFs

What kind of routing are you using for the vrf's? Do the ip address
ranges overlap?
You can set up a single BGP address-family vrf process with no
peering. You just redistribute the connected interfaces and vrf
routing processes (i.e. static).

ip vrf A
 rd 10:1
 route-target export 10:1
 route-target import 10:2
!
ip vrf B
 rd 10:2
 route-target export 10:2
 route-target import 10:1
!

interface FastEthernet1/0
 ip vrf forwarding A
 ip address x.x.x.x
 duplex auto
 speed auto
 no clns route-cache
!
!
interface FastEthernet2/0
 ip vrf forwarding B
 ip address x.x.x.x
 duplex auto
 speed auto
 no clns route-cache
!

router bgp 10
 no synchronization
 bgp log-neighbor-changes
 no auto-summary
 !
 address-family ipv4 vrf A
 redistribute connected
 redistribute static
 no auto-summary
 no synchronization
 exit-address-family
 !
 address-family ipv4 vrf B
 redistribute connected
 redistribute static
 no auto-summary
 no synchronization
 exit-address-family
!
!

(static routes pointing to next hop out the respective interface to
the vrf networks)
ip route vrf A x.x.x.x..x.xxx.
ip route vrf B x.x.x.x...xx.xx
!
