Abstract

In a first-hop router, a reachability monitor monitors RP (Rendezvous-Point) reachability, and the number of times when a response time is not shorter than a predetermined time is stored in a RP management table. An RP selection process controls not to select RP whose reachability from the first-hop router is not stable, so that PIM Register transmission to an unstable RP is suppressed.
