Step 2 interface tunnel-te interface-number
Example:
RP/0/RSP0/CPU0:router(config)#interface
tunnel-te 65535
Step 3 bfd dampening initial-wait milliseconds
Example:
RP/0/RSP0/CPU0:router(config-if)#bfd
dampening initial-wait 360000
Step 4 bfd dampening maximum-wait milliseconds
Example:
RP/0/RSP0/CPU0:router(config-if)#bfd
dampening maximum-wait 700000
Step 5 bfd dampening secondary-wait milliseconds
Example:
RP/0/RSP0/CPU0:router(config-if)#bfd
dampening secondary-wait 30000

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.

Purpose
Configures MPLS Traffic Engineering (MPLS TE) tunnel interface
and enters into MPLS TE tunnel interface configuration mode.
Configures the initial delay interval before bringing up the tunnel.
The initial-wait bring up delay time interval range is 1 to 518400000
milliseconds. Default initial-wait interval is 16000 milliseconds.
This option brings up the TE tunnel with the previous
Note
signaled bandwidth.
Configures the maximum delay interval before bringing up the tunnel.
The maximum-wait bring up delay time interval range is 1 to
518400000 milliseconds. Default initial-wait interval is 600000
milliseconds.
This option brings up the TE tunnel with the configured
Note
bandwidth.
Configures the secondary delay interval before bringing up the tunnel.
The secondary-wait bring up delay time interval range is 1 to
518400000 milliseconds. Default secondary-wait interval is 20000
milliseconds.
