When refresh messages are not received, RSVP path states and resource reservations are removed from the routers in an LSP. By default, the device waits the length of three refresh intervals; when no refresh message is received by the end of that time, the path state or resource reservation is removed.
The user can set the refresh multiple from zero through 65535 intervals.
Complete the following steps to set the refresh multiple to five intervals.device# configure
device(config)# router mpls
device(config-router-mpls)# rsvp
device(config-router-mpls-rsvp)# refresh-multiple 5
The following example shows setting the refresh multiple to 5.
device# configure device(config)# router mpls device(config-router-mpls)# rsvp device(config-router-mpls-rsvp)# refresh-multiple 5
