For routers or switches with multiple Routing Engines, control which Routing Engine is
the master.
CAUTION: (Routing matrix based on the TX Matrix or TX Matrix Plus routers
only) Within the routing matrix, we recommend that all Routing Engines run
the same Junos OS Release. If you run different releases on the Routing
Engines and a change in mastership occurs on any backup Routing Engine in
the routing matrix, one or all T640 routers (in a routing matrix based on the
TX Matrix router) or T1600 routers (in a routing matrix based on a TX Matrix
Plus router) might become logically disconnected from the TX Matrix router
and cause data loss. For more information, see the TX Matrix Router Hardware
Guide or the Junos OS High Availability Configuration Guide.
NOTE: Successive graceful Routing Engine switchover events must be a
minimum of 240 seconds (4 minutes) apart after both Routing Engines have
come up.
If the router or switch displays a warning message similar to "Standby Routing
Engine is not ready for graceful switchover. Packet Forwarding Engines that
are not ready for graceful switchover might be reset," do not attempt
switchover. If you choose to proceed with switchover, only the Packet
Forwarding Engines that were not ready for graceful switchover are reset.
None of the Flexible PIC concentrators (FPCs) should spontaneously restart.
We recommend that you wait until the warning no longer appears and then
proceed with the switchover.
