Statement introduced before JUNOS Release 7.4.

Description

When the on-loss-of-keepalives statement is included but graceful Routing Engine switchover is not configured, failover occurs after 300 seconds (5 minutes).

When the on-loss-of-keepalives statement is included and graceful Routing Engine switchover is configured, the keepalive signal is automatically enabled and the failover time is set to 2 seconds (4 seconds on M20 routers) . The keepalive time is not configurable.
