Hi Fellows,
Please i need help, i have been trying to troubleshoot these topology, I created an MPLS VPN (design/ configs attached), but the ISP3R can't ping ISP1R VRF. Everything looks okay with the config.
ISP2R and attached CE can ping ISP1R and attached CE's but ISP3R can't ping across the configured P routers (ISP5R and ISP6R). But the Routes all show up in the Routing tables/ VRF table,
when i use: sh bgp vpnv4 unicast
Please kindly help. I'm doing this on a Cisco VIRL using the IOS XR as the Provider Network and IOSv as the Customer edge.
Attached are the design and config.
