Juniper MX104 - Taking an MX104 Routing Engine Offline

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
configurationon 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 statement. For instructions, see the Junos OS
Administration Library.

NOTE: Forinformationabout configuring graceful Routing Engine switchover,
graceful restart,and nonstopactive routing, see the Junos OS High Availability
Library for Routing Devices.
NOTE: 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 Library for Routing
Devices.
Taking an MX104 Routing Engine Offline
Before you take a Routing Engine offline, see “Effect of Taking the MX104 Routing Engine
Offline” on page 152.
To take the Routing Engine offline:
1. Determine whether the Routing Engine is functioning as the master or as the backup,
using one of the two following methods:
•
If the MASTER LED on the Routing Engine is lit, that Routing Engine is functioning
as the master.
•
Issue the show chassis routing-engine command.
user@host> show chassis routing-engine
Routing Engine status:
Slot 0:
Current state Master
Election priority Master (default)
The master Routing Engine is designated Master in the current state field.
