Hello Experts,
I have simple MPLS topology running OSPF betwen CE-PE and MP-BGP. When I
change domain-id on PE, I can't see the change in real domain-id by running
show bgp vpnv4 unicast vrf VPN_A 172.16.8.0, but still the OSPF route type
changes to E2.
C1 - PE1 - RR - PE2 - C2
Both C routers running OSPF between PE with same OSPF process number.
The command output as below:
PE1
Rack1R6#show bgp vpnv4 unicast vrf VPN_A 172.16.8.0

Should I not be seeing different domain-id for this route; however, both of
them shows 63- When I see routes on C routes it changes to E2 and when I
remove the domain-id's, I see routes as IA.
Any help will be highly appreciated.
Thanks,
Bilal Hansrod
