Description 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 High Availability Configuration Guide.
