Cisco ASR 9000 Series Configuration Guide

PurposeCommand or Action
Configures MPLS Traffic Engineering (MPLS TE) tunnel interface
and enters into MPLS TE tunnel interface configuration mode.
interface tunnel-te interface-number
Example:
RP/0/RSP0/CPU0:router(config)#interface
tunnel-te 65535
Step 2
Sets periodic interval for LSP ping requests or disables LSP ping
requests.
Use one of these commands:
Step 3
•
bfd lsp-ping interval 300
• interval seconds—Sets periodic LSP ping request interval in
seconds. The interval range is 60 to 3600 seconds. Default interval
is 120 seconds.
Example:
RP/0/RSP0/CPU0:router(config-if)#bfd
lsp-ping interval 300
• disable—Disables periodic LSP ping requests.
Or
RP/0/RSP0/CPU0:router(config-if)#bfd
lsp-ping disable
Periodic LSP ping request is enabled by default. The default interval
for ping requests is 120 seconds. BFD paces LSP ping to be under 50
ping per seconds (PPS). Thus ping interval is honored; however, this
is not guaranteed unless configuring an interval between 60 and 3600
seconds.

What to Do Next
Configure BFD at the tail-end.
Configuring BFD at the Tail End
Use the tail end global configuration commands to set the BFD minimum-interval and BFD multiplier
parameters for all BFD over LSP sessions. The ranges and default values are the same as the BFD head end
configuration values. BFD will take the maximum value set between head end minimum interval and tail end
minimum interval.
Perform these tasks to configure BFD at the tail end.
