Couldn't you just run a VPNV4 global session between RA and RB for the routes.
You would then import/export the relevant RT's in the different VRF's ? or am I missing something here.

Since you are using VRF-lite, you really have 3 separate 'routers' on RA and
RB, so yes you need 3 iBGP sessions between them to have connectivity within
the VRF

Experts,
Need your advise,
I am running VRF lite on a pair of CE (RA and RB) and connected to
a
pair of PE ( RC and RD) using EBGP, currently I have 3 VRFs
RA---------------------------RC
|
|
|
RB----------------------------RD
The question is, should I create 3 IBGP session between RA and RB
hence-
1 session each in address family ipv4 vrf config... or it just need 1
IBGP session between RA and RB.
From my understanding is, as there are 3 VPN logically separated, then
there should be 3 IBGP session. Or both are viable ? Advantages ?
Disadvantages?
Thanks
