By default, a higher-priority backup router preempts a lower-priority master router.
4.
To explicitly enable the master router to be preempted:
[edit interfaces interface-name unit logical-unit-number family inet6
address address vrrp-inet6-group group-id]
user@switch# set preempt
To prohibit a higher-priority backup router from preempting a lower priority master
router:
[edit interfaces interface-name unit logical-unit-number family inet6
address address vrrp-inet6-group group-id]
user@switch# set no-preempt

Nonstop active routing (NSR) provides a mechanism for transparent switchover of the
Routing Engines without necessitating restart of supported routing protocols. Both Routing
Engines are fully active in processing protocol sessions, and so each can take over for
the other. The switchover is transparent to neighbors.
You can configure nonstop active routing on an EX Series switch with redundant Routing
Engines to enable the transparent switchover of the Routing Engines in the event that
the Routing Engines switch over. You can also disable nonstop active routing after you
have enabled it.
To configure nonstop active routing:
Enable graceful Routing Engine switchover (GRES):
1.
[edit chassis redundancy]
user@switch# set graceful-switchover
Enable nonstop active routing (by default, nonstop active routing is disabled):
2.
[edit routing-options]
user@switch# set nonstop-routing
Synchronize configuration changes between the Routing Engines:
3.
[edit system]
user@switch# set commit synchronize
If you try to commit the nonstop active routing configuration without including the
commit synchronize statement, the commit fails.
