    Syntax

    on-loss-of-keepalives;

    Hierarchy Level

    [edit chassis redundancy failover]

    Release Information

    Statement introduced before Junos OS Release 7.4.

    Description

    Instruct the backup router to take mastership if it detects a loss of keepalive signal from the master Routing Engine.

    Default

    The on-loss-of-keepalives statement must be included at the [edit chassis redundancy failover] hierarchy level for failover to occur.

    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.
