I have lab scenario working on L3 VPN to test for the environment where PE connection to two MPLS P providers. In my lab shows only one MPLS provider(P1 and P2)
CE1<->PE1<->P1<->P2<->PE2<->CE2
However in PE both sites, route learning between PE and P are under VRF, not in global routing.
CE1<->(vrf B)PE1=PE1(vrf A)<->P1<->P2<->(vrf A)PE2=PE2(vrf B)<->CE2
I created tunnel VRF within PE to bridge global routing and VRF A.
I have loopback99 in both PEs global routing using for MBGP source address, MBGP is up properly.
I can see VPN routes from CE1 and CE2 exchanges throuhg BGP both sites.
The problem is I couldn't get response while ping from CE1 to CE2 address (VRF B). From first glance, it might cause from labeling between global routing and VRF A.
