Configuring Periodic LSP Ping Requests

Configuring Periodic LSP Ping Requests
Perform this task to configure sending periodic LSP ping requests with BFD TLV, after BFD session comes
up.
Before you begin
BFD must be enabled under MPLS TE tunnel interface.
SUMMARY STEPS
1. configure
2. interface tunnel-te interface-number
3. Use one of these commands:
4. commit
DETAILED STEPS
Command or Action
Step 1
configure
Step 2
interface tunnel-te interface-number
Example:
RP/0/RP0/CPU0:router(config)#interface tunnel-te
65535
Step 3 Use one of these commands:
• bfd lsp-ping interval 300
Example:
RP/0/RP0/CPU0:router(config-if)#bfd lsp-ping
interval 300
Or
RP/0/RP0/CPU0:router(config-if)#bfd lsp-ping
disable
Step 4 commit
What to do next
Configure BFD at the tail-end.

• bfd lsp-ping interval 300
Purpose
Configures MPLS Traffic Engineering (MPLS TE) tunnel
interface and enters into MPLS TE tunnel interface
configuration mode.
Sets periodic interval for LSP ping requests or disables LSP
ping requests.
• interval seconds—Sets periodic LSP ping request
interval in seconds. The interval range is 60 to 3600
seconds. Default interval is 120 seconds.
• disable—Disables periodic LSP ping requests.
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.
