Usage Guidelines

Usage Scenario

After a TE tunnel has been established, the TE tunnel is kept Up by periodically sending a Path message from the local node to its neighbor and receiving a Resv message from the neighbor. If no Resv message is received after the specified interval at which a tunnel is re-established, the local node considers the tunnel Down and reattempts to establish the tunnel. You can run this command to modify the interval for re-establishing a tunnel.

Precautions

A rather smaller interval imposes heavy burden of message processing on the system, causing network flapping; a rather large interval deteriorates the efficiency of RSVP CR-LSP convergence. Therefore, the default interval, 30 seconds, is recommended.

Example

# Set the interval for setting up tunnels to 20 seconds.
