NOTE:

Router performance might change if the backup Routing Engine's

configuration differs from the former master's configuration. For the most
predictable performance, configure the two Routing Engines identically,
except for parameters unique to each Routing Engine.

To configure Routing Engine-specific parameters and still use the same
configuration on both Routing Engines, include the appropriate configuration
statements under the

re0

and

re1

statements at the [

edit groups

] hierarchy

level and use the

apply-groups

staement. For instructions, see the Junos OS

System Basics Configuration Guide.

NOTE:

For information about configuring graceful Routing Engine switchover,

graceful restart, and nonstop active routing, see the Junos OS High Availability
Configuration Guide.

NOTE:

The first supported release for both graceful Routing Engine switchover

and nonstop active routing on the router is Junos OS Release 9.0. Graceful
restart software requirements depend on the routing protocols configured
on the router. For the minimum software requirements for graceful restart,
see the Junos OS High Availability Configuration Guide.
