Hierarchy Level



[edit chassis redundancy]

Release Information

Statement introduced before JUNOS Release 7.4.

Description

Configure the time period that must elapse before the backup router takes mastership when it detects loss of the keepalive signal.

Default

If the failover on-loss-of-keepalives statement at the [edit chassis redundancy] hierarchy level is not included and graceful Routing Engine switchover (GRES) is not enabled, failover cannot occur.

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

When the failover 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. You cannot manually reset the keepalive time.

Options

seconds—Time before the backup router takes mastership when it detects loss of the keepalive signal. The range of values is 2 through 10,000.
