[j-nsp] Strange OSPF Issue over MPLS VPN with PE-CE as OSPF !

[vaibhava varma]

Hi Ivan

I finally got the routes on the VRF-Lite CE by using two commands on the PE

domain-id disable
domain-vpn-tag 0


I have a dual homed setup with two PE and 2 VRF-Lite CE. Will this not
cause routing loop because the CEs will share the route and will send
the routes back to other PE which will have an MP-iBGP route with
preference 170 and OSPF route with preference 10/150.

Regards
Varma
