Effect of a Change in Mastership
You or a host subsystem initiates a change in mastership to the backup Routing Engine in
the TX Matrix Plus router—The master Routing Engines in the T1600 routers detect a software
[edit
release mismatch with the new master Routing Engine in the TX Matrix Plus router and
switch mastership to their backup Routing Engines.
You attempt to initiate a change in mastership to a backup Routing Engine in a T1600
router—The new master Routing Engine in the T1600 router detects a software release
mismatch with the master Routing Engine in the TX Matrix Plus router and relinquishes
mastership to the original master Routing Engine. Routing Engine mastership in the TX Matrix
Plus router does not switch in this case.
A host subsystem initiates a change in mastership to a backup Routing Engine in a T1600
router because the master Routing Engine has failed—The T1600 router is logically
disconnected from the TX Matrix Plus router.
You initiate a change in mastership to the backup Routing Engine in the TX Matrix Plus
router—All T1600 routers are logically disconnected from the TX Matrix Plus router.
You initiate a change in mastership to a backup Routing Engine in a T1600 router—The
T1600 router is logically disconnected from the TX Matrix Plus router. To reconnect the
T1600 router, switch mastership of the new master Routing Engine in the T1600 router back
to the original master Routing Engine.
