What to Do Next
Configure BFD dampening parameters to bring up the TE tunnel and to avoid signaling churn in the network.
Configuring BFD Dampening for TE Tunnels
When BFD session fails to come up, TE exponentially backs off using the failed path-option to avoid signaling
churn in the network.
Perform these steps to configure dampening intervals to bring the TE tunnel up.
Before You Begin
• BFD must be enabled under MPLS TE tunnel interface.
• BFD bring up timeout interval must be configured using the bfd bringup-timeout command.

Purpose
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

signaled bandwidth.
