Checking the Configurations

Checking the Configurations

After configuring inter-AS seamless MPLS+HVPN, you can check all BGP peer relationships, VPNv4 routing information on AGGs and MASGs, and the connectivity of the BGP LSP between each pair of an AGG and MASG.

Prerequisites

Inter-AS seamless MPLS+HVPN has been configured.

Procedure

  • Run the display bgp vpnv4 all peer command on an AGG or MASG to check BGP peer relationship information.
  • Run the display bgp vpnv4 all routing-table command to check the VPNv4 routing table on an AGG or MASG.
  • Run the display bgp routing-table label command on an AGG, AGG ASBR, core ASBR, or MASG to check label information of IPv4 routes.
  • Run the display ip routing-table vpn-instance vpn-instance-name command to check the VRF table on an AGG or MASG.

Example

# Run the display bgp vpnv4 all peer command on an AGG or MASG. The command output shows that an EBGP peer relationship between two PEs is Established.

Run the display bgp vpnv4 all routing-table command on an AGG or MASG. The command output shows that BGP VPNv4 routes and BGP VPN instance routes are reachable on the PE, not on the ASBR.
