Configuring RSVP-TE Protocol Parameters
To configure RSVP-TE protocol parameters, use the following command:
config mpls rsvp-te vlan [<name> | all] {hello-interval <seconds>}
{refresh-time <seconds>} {summary-refresh-time <seconds>} {bundle-time
<seconds>} {keep-multiplier <number>}
This command configures the RSVP-TE protocol parameters for the specified VLAN.
