i have the following setup:
R1----R2---R3---R4---R5
R1 and R5 are CE routers
R2 and R4 are PE routers
R3 is a P router
i have OSPF running as the underlining IGP between R2, R3 and R4, then i
have MP-BGP running between the 2 PEs (R2 and R4)
CE R1 uses EIGRP as the routing protocol of choice with PE R2, and CE R5
uses RIP to talk to PE R4.
LDP configured across R2, R3 and R4.
Single VRF called HOME on both PEs.
Routes are propagating across the PEs fine, but when from R1 between R5
(sourcing from known ip to the remote end), it fails. So i moved closer and
attempted ping between R2 and R4. fails too.
On R2, R4's loopback (4.4.4.4) is listed as the next hop to all routes
beyond it. But recursive lookup on 4.4.4.4 from R2's VRF CEF and LFIB tables
fail
Any suggestions would be appreciated!!!
