Configuring MPLS ping for LSPs
Perform the following task in any view:
Task Command
Use MPLS ping to verify MPLS LSP connectivity
for an IPv4 prefix.
ping mpls [ -a source-ip | -c count | -exp exp-value | -h
ttl-value | -m wait-time | -r reply-mode | -rtos tos-value | -s
packet-size | -t time-out | -v ] * ipv4 dest-addr mask-length
[ destination start-address [ end-address
[ address-increment ] ] ]
Configuring MPLS traceroute for LSPs
Perform the following task in any view:
Task Command
Use MPLS traceroute to trace the LSPs
for an IPv4 prefix.
tracert mpls [ -a source-ip | -exp exp-value | -h ttl-value | -r
reply-mode | -rtos tos-value | -t time-out | -v | fec-check ] * ipv4
dest-addr mask-length [ destination start-address [ end-address
[ address-increment ] ] ]
Configuring periodic MPLS traceroute for LSPs
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enable periodic LSP
traceroute for an FEC.
mpls periodic-tracert dest-addr mask-length
[ -a source-ip | -exp exp-value | -h ttl-value |
-m wait-time | -rtos tos-value | -t time-out | -u
retry-attempt | fec-check ] *
By default, periodic LSP
traceroute is disabled.
Configuring MPLS BFD for LSPs
To configure MPLS BFD for an LSP, configure both the local and remote devices as described in Table 42.
Table 42 Configurations on the local and remote devices
BFD session
establishment
mode
Node type
Execute the "mpls bfd
enable" command?
Execute the
"mpls bfd"
command?
Configure the
discriminator keyword?
Static mode
Local Yes Yes Yes
Remote Yes Yes Yes
Dynamic mode
Local Yes Yes No
Remote Yes No N/A
Follow these guidelines to configure BFD for an LSP tunnel:
• To establish a static BFD session, ensure that the local and remote discriminators configured locally
are identical with the remote and local discriminators configured on the remote device, respectively.
