DECnet: Router or End Node Sees Incorrect Designated Router
Possible Problem
Solution
Priority of the
expected
designated router is
not configured
correctly
1. Use the show decnet interface exec command to
determine which router is the designated router. Note the
priority of the router that is shown in the command output.
2. If the designated router identified in the output is not the
correct router, use the show decnet interface command on
the expected designated router and the actual designated
router.
3. Compare the priority of the actual designated router with
that of the expected designated router. The router that you
want to be the designated router should have the highest
priority.
Syntax:
4. If necessary, use the decnet router-priority interface
configuration command to give a higher priority to a router
so that it will be elected the designated router.
The following is the syntax for the decnet router-priority
command:
decnet router-priority value
To elect a designated router to which packets will be sent when
no destination is specified, use the decnet router-priority
interface configuration command.
Syntax:
value —Priority of the router. This can be a number in the
range 0 through 127. The larger the number, the higher the
priority. The default priority is 64.
Multiple routers
have the same
router priority
1.
Use the show decnet interface command to determine
which router is the designated router. Note the priority of
the router that is shown in the command output.
2.
Use the show decnet interface command on the expected
designated router and compare the priorities of the actual
and the expected designated routers.
3.
If the routers have the same priority, use the
decnet router-priority interface configuration command
to configure a higher priority on the router that should be
elected the designated router.
