OS for EX Series Ethernet Switches, Release 10.4
The topology used in this example consists of an EX8200 switch with redundant Routing
Engines connected to neighbor routing devices that are not configured to support graceful
restart of protocols.
To quickly configure nonstop active routing, copy the following commands and paste
them into the switch terminal window:
[edit]
set chassis redundancy graceful-switchover
set routing-options nonstop-routing
set system commit synchronize
To configure nonstop active routing on a switch:
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.
NOTE: If the backup Routing Engine is down when you issue the commit,
a warning is displayed and the candidate configuration is committed in
the master Routing Engine. When the backup Routing Engine comes
up, its configuration is automatically synchronized with that of the
master. If you subsequently insert or bring up a backup Routing Engine,
it automatically synchronizes its configuration with the master Routing
Engine configuration.
Check the results of the configuration:
[edit]
user@switch# show
chassis {
redundancy {
graceful-switchover;
}
routing-options {
nonstop-routing;
}
system {
