I configured the MPLSVPN in my test topology which is chain of 6 router 1 and 6 routers are CE routers and all other are for provier network in which 2 and 5 is PE1 and PE2 router, as PE-CE communication i am using RIP, In both the CE router i have configured 3 loop back interface as internal network.
Here i can see the loopback of each other CEs in their routing tables but i cannot able to ping those loopbacks why?
other strang thing is i can not ping the PE routers interface which are connected with the CE routers so i want to know why i cannot ping the PE routers interface facing to CE routers?
How can i make all those loopback reachable to each other?
Dan, how are you trying to ping. I am sure you are using the "ping vrf "
If you use the plain ipv4 ping like "ping " it wpont work.
