Monitoring and Maintaining the MPLS VPN Chapter 3 Configuring Remote Access to MPLS VPN Verifying the PE to CE Routing Protocol If the CE router uses a routing protocol other than BGP (for example, RIP or OSPF), enter any of the following commands in privileged EXEC mode to verify the PE to CE routing sessions: Command Router# show ip rip database vrf vrf-name Router# show ip ospf [process-id [area-id]] database Purpose Displays summary address entries in the Routing Information Protocol (RIP) routing database for the specified VRF. Displays lists of information related to the OSPF database for a specific router. Note The show ip rip database vrf and show ip ospf commands are useful for verifying the routing table from the CE router side of the connection and for determining if neighbors are missing from the routing table. Verifying the MPLS VPN Labels An MPLS VPN uses a transport label to identify the VRF and another label to identify the backbone. To verify the MPLS VPN labels, enter any of the following commands in privileged EXEC mode: Command Router# traceroute vrf vrf-name ip-address Router# show ip bgp vpnv4 all tags Purpose Displays the transport addresses for the specified VRF. Ensure that the interfaces displayed are the correct cross-connect addresses. Displays the labels for a particular VRF. Note The traceroute vrf command works with an MPLS-aware traceroute, and only if the backbone ATM switch routers are configured to propagate and generate IP Time to Live (TTL) information. Example 3-26 traceroute vrf Command Router# traceroute vrf vrf-1 192.168.1.1 Type escape sequence to abort.
