keepalive-time (Chassis)
Syntax
keepalive-time seconds;
Hierarchy Level
[edit chassis redundancy]
Description
Configure the time period that must elapse before the backup router takes primary role when it detects loss of the keepalive signal.
Default
The on-loss-of-keepalives statement at the [edit chassis redundancy failover] hierarchy level must be
included for failover to occur.
When the on-loss-of-keepalives statement is included
and 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). You cannot manually
reset the keepalive time.
