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 Configuring BGP Routing . See 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.

Note: The E120 router and E320 router output for monitor and show commands is identical to output from other E-series routers, except that the E120 and E320 router output also includes information about the adapter identifier in the interface specifier (slot/adapter/port).

debug ip mbgp

• Use to display information about MP-BGP logs for inbound or outbound events, or both.
• Example

  host1#debug ip mbgp

• There is no no version, but you can use the undebug ip mbgp command to disable display of information previously enabled with the debug ip mbgp command.
• See 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
• Examples

show mpls l2transport load-balancing-group

• Use to display information about load-balanced Martini circuits.
• 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.
• Use the member-circuits keyword to display circuit information for the group.
• Field descriptions
  • routed to/base LSP—Identifies address of the router at the other end of the tunnel and the base tunnel that is selected to forward the traffic
  • load-balancing group—Group number
  • Martini group-id—Martini group ID number for the interface
  • state—State of the interface
  • vc-id—VC ID number for the interface
  • mtu—Maximum transmission unit for the interface
  • In label—Label sent to upstream neighbor for route; statistics below this field are the aggregate statistics for traffic from the core
  • Out label—Label received from downstream neighbor for route; statistics below this field are the aggregate statistics for traffic to the core
  • pkts—Number of packets sent across tunnel
  • hcPkts—Number of high-capacity (64-bit) packets sent across tunnel
  • octets—Number of octets sent across tunnel
  • hcOctets—Number of high-capacity (64-bit) octets sent across tunnel
  • errors—Number of packets dropped for some reason before being sent
  • queue 0—Number of the queue for which statistics are being displayed and whether the queue is under traffic class control
  • traffic class—Name of traffic class
  • bound to—Interface to which queue is bound
  • Queue length—Size of queue in length and bytes
  • Forwarded—Number of forwarded packets and bytes
  • Dropped committed—Number of committed packets and bytes dropped
  • Dropped conformed—Number of conformed packets and bytes dropped
  • Dropped exceeded—Number of exceeded packets and bytes dropped
  • discardPkts—Number of packets discarded due to lack of buffer space before being sent
  • Member Interfaces—Information about the member interfaces for the circuit
  • Interface—Interface specifier and status; active indicates it is being used for traffic from the core; if active is not displayed, interface is not currently being used for traffic, but the statistics may be valid
  • member ports—Number and type of candidate ports configured for the group, including interface specifiers and state
  • member circuits—Number of member circuits configured for each port and for the group

show mpls tunnels

• Use to display status and configuration for all tunnels or for a specific tunnel in the current router context.
• A result of Incomplete Configuration in the display indicates either no tunnel endpoint or no label distribution protocol.
• Field descriptions
  • State—Status of tunnel, up or down
  • Out Label—In the default case for a BGP/MPLS VPN, the Variable Interface, which indicates that a packet exiting the interface is going through a variable interface and that one of the labels listed further in the display will be prepended to the packet
  • Mpls Statistics
    • pkts—Number of packets sent across tunnel
    • hcpkts—Number of high-capacity (64-bit) packets sent across tunnel
    • octets—Number of octets sent across tunnel
    • hcoctets—Number of high-capacity (64-bit) octets sent across tunnel
    • errors—Number of packets that are dropped for some reason before being sent
    • discardPkts—Number of packets that are discarded due to lack of buffer space before being sent
  • Labels—List of labels associated with the variable interface; one will be selected to be prepended to packets before being sent across tunnel
