Possible Problem Solution
Priority of the
expected designated
router is not
configured correctly
Step 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.
Step 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.
Step 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:
Step 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
Step 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.
Step 2 Use the show decnet interface command on the expected designated router and
compare the priorities of the actual and the expected designated routers.
Step 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.
Syntax:
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.
Note: If two routers are configured with the same
priority, the router with the higher node number will
become the designated router.
