Abstract

This memo addresses an issue with the current PIM in Sparse Mode. In the case of router reboot, PIM networks have to converge slowly and suffer long outage of traffic flows. This memo proposes a Generation Identifier (GenId) Option in PIM Hello messages. It enables neighbors to quickly detect router reboot and thus to synchronize RP-Set information and forwarding states by triggering Bootstrap and Join/Prune messages to the rebooted router. The rebooted router then is able to quickly recover from the reboot.
