IS-IS SPRING and RSVP coexistence

The routing protocol process (rpd) takes into account the bandwidth used by SPRING traffic to calculate the balance bandwidth available for RSVP-TE. The allocated bandwidth for RSVP is periodically modified based on the traffic on the SPRING interface and its bandwidth utilization. To configure automatic bandwidth calculation, include the auto-bandwidth template statement at the [edit routing-options] hierarchy level. You can apply the auto-bandwidth template configuration either globally at the [edit protocols isis source-packet-routing traffic-statistics] hierarchy level or at the [edit protocols isis interface interface-name] hierarchy level. This feature is useful for networks that are moving to SPRING but also have RSVP deployed, and continue to use both SPRING and RSVP.
