Monitoring BGP/MPLS VPNs
To view BGP/MPLS VPN settings, you can issue the following show commands as well as any of the show ip bgp commands and some of the show bgp ipv6 commands described in Chapter 1, Configuring BGP Routing. See Chapter 2, Configuring MPLS, for information about show commands to monitor MPLS settings.
Use the debug ip mbgp command to get information about problems with BGP or the network.
debug ip mbgp
host1#debug ip mbgp
show ip bgp next-hops
- Use to display information about BGP next hops.
- Specify all VRFs or a particular VRF, and all indirect next hops or a particular indirect next hop.
- Field descriptions
- Indirect next-hop—BGP next-hop attribute as received in the BGP update message
- Resolution—Describes where the indirect next hop is resolved: the IP routing table, the IP tunnel routing table, or both, and whether this is in a VR or VRF
- IP indirect next-hop index—Index number of the IP indirect next hop that this BGP indirect next hop resolves to
- MPLS indirect next-hop index—Index number of the MPLS indirect next hop that this BGP indirect next hop resolves to
- Reachable—Indicates whether or not the indirect next hop is reachable.
For labeled unicast routes, the following rules apply:
- When it is received from a nonmultihop peer, the indirect next hop is reachable if the MPLS major interface next to the peer IP interface exists and is operationally up.
- When it is received from other types of peers,the indirect next hop is reachable if an entry exists in the IP tunnel routing table that resolves this indirect next-hop address.
For unlabeled unicast routes, the following rules apply:
- When it is received from an nonmultihop peer, the indirect next hop is reachable through the directly connected peer interface.
- When it is received from other type of peers, the indirect next hop is reachable if an entry exists in the IP routing table that resolves this indirect next-hop address.
For VPN labeled routes in a VRF, the following rules apply:
- When it is received in a core VRF from a remote multihop IBGP or EBGP VPN peer, the indirect next hop is reachable if an entry exists in the IP tunnel routing table that resolves the next-hop address.
- When it is received in a core VRF from a nonmultihop peer, the indirect next hop is reachable if the MPLS major interface next to the peer IP interface exists and is operationally up.
- Metric—Metric of the BGP indirect next hop
- Number of direct next-hops—Number of the equal-cost legs of direct next hops that this indirect next hop resolves to
- Direct next-hop—IP interface and next-hop IP address that resolve the BGP indirect next hop; the direct next hop can also be an IP indirect next hop or an MPLS indirect next hop when chains of next hops are in use
- Reference count—Number of label mappings of BGP routes that use this next hop

- For a simpler view, the show mpls l2transport interface command displays only the currently active VLAN or S-VLAN subinterface. Because load-balanced circuits are configured on subinterfaces on multiple ports, only one of which is active at a given time, this command does not give a complete picture of the configuration.
