Network Failure IGP는 오류가 발생한 후 복구 작업(경로 계산)이 수행됨 RSVP-TE는 장애가 발생하기 전에 조치를 취할 수 있음 LDP를 사용하면 IGP 의존성 때문에 수렴 시간이 IGP 수렴에 의존함 Failure Type - Local vs Remote Local Failure는 즉시 감지됨 - 라우터는 Local Port가 Down됨 Remote Failure의 경우 보통 라우터 포트는 UP 상태를 유지할 수 있음 - 라우터는 Neighbor 관계가 Down 되었음을 감지하기 위해 IGP 또는 RSVP Hello와 같은 메커니즘에 의존함 Failure Detection Protocol IGP Hello - Default Timer를 사용하면 Neighbor Down을 감지하는 데 약 30s 소요 RSVP Hello - Default Timer를 사용하면 Neighbor Down을 감지하는 데 약 9s 소요 IGP 및 RSVP Hello Timer...
