Good Morning,
i have issue with below Topology, where R16 and R1 have each other routes but not reachable, the packet get drop from directly connected PE,
Details :- XR4 (11.11.11.11/32) and R3 (8.8.8.8/32) both advertise their local PE loopback address using BGP labled protocol,
- XR4 reddtribute learned routes (8.8.8.8/32) to OSPF 1.
- R3 Redistribute learned routes (11.11.11.11/32) to OSPF 321.
- XR1 and R8 form vpnv4 neighbour from Redistributed routes by XR4 & R3(Ebgp-lulti-hop).
- XR4 has static routes towards R3 using /32 (for label support).
- R8 redistribute vpnv4 learned routes to vrf X (address-family ipv4 vrf X
redistribute eigrp 100) (router eigrp 100 address-family ipv4 vrf X autonomous system 100 redistribute bgp 321 metric 1000 10 255 1 1500). - XR1 has Ibgp neighbor to CE router, also vrf export and Import done according to isp-2 R8 router.
