Checking the Configurations

Checking the Configurations

After configuring inter-AS seamless MPLS, you can check the established LSPs and the connectivity of the BGP LSP between the CSG and MASG.

Prerequisites

Inter-AS seamless MPLS has been configured.

Procedure

  • Run the display ip routing-table command on the CSG and MASG to check the route to each other.
  • Run the display mpls lsp command to check LSP information.
  • Run the ping lsp [ -a source-ip | -c count | -exp exp-value | -h ttl-value | -m interval | -r reply-mode | -s packet-size | -t time-out | -v ] * bgp destination-iphost mask-length [ ip-address ] command on a CSG or MASG to check BGP LSP connectivity.

Example

Run the display ip routing-table command on a CSG or MASG to view information about a route to a BGP peer.

<CSG> display ip routing-table
Route Flags: R - relay, D - download
to fib, T - to vpn-instance, B - black hole route

Run the display mpls lsp command to view LSP information.

Run the ping lsp command on a CSG or MASG to check BGP LSP connectivity.
