I have a topology of MPLS VPN like this

And my problem is my teacher ask me to configure one site with RIP routing protocol between PE1 and CPE1; another one with OSPF routing protocol between PE2 and CPE2. And this is my problem, i dont know how to do that. If configure two site RIP-RIP or OSPF-OSPF, i can practice immetately but with this problem, i dont know how to start.

Help me with configuration MPLS VPN 1 site Rip and 1 site OSPF

Hi Cuong,

Can you let me know what exact problem you are facing, are you able to see route of one site on another ?

Can you try redistributing OSPF into bgp with below command

"redistribute ospf 2 match internal external 1 external 2"

Can you provide "show ip route vrf A" of both PE1 and PE2, and show ip route on CE1 and CE2.

Regards,

Sandip
