CAUTION
Run the reset mpls ldp command to reset configurations of the global LDP instance.
Run the reset mpls ldp all command to reset configurations on all LDP instances.
Run the reset mpls ldp peer peer-id command to reset a specified peer.
Run:
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 ]
address mask-length [ ip-address ] [ nexthop nexthop-address | draft6 ]
MPLS ping is performed.
If draft6 is specified, the command is implemented according to draft-ietf-mpls-lsp-
ping-06. By default, the command is implemented according to RFC 4379.
Run:
tracert lsp [ -a source-ip | -exp exp-value | -h ttl-value | -r reply-mode | -
*
t time-out ] ip destination-address mask-length [ ip-address ] [ nexthop
nexthop-address | draft6 ]
MPLS tracert is performed.
If draft6 is specified, the command is implemented according to draft-ietf-mpls-lsp-
ping-06. By default, the command is implemented according to RFC 4379.
