Specifying Router Priority for a Multiaccess Network

The router priority value is used in multiaccess networks (broadcast, NBMA, or

point-to-multipoint) to elect the designated router. A router with a priority of 0 is

not eligible to become the designated router on this particular network.

In the case of equal router priority values, the router ID determines which router

becomes the designated router. However, if there already is a designated router on

the network when you start this router, it will remain the designated router no

matter what your priority or router ID.

By default, each OSPF interface has a router priority of 1.

You can use the BCC or Site Manager to do the following:

• Specify a priority value for the interface.

• Make the router ineligible to be the designated router on this interface.

Using the BCC

To specify a router priority value, navigate to an OSPF interface prompt (for

example,

box; eth 2/2; ip/2.2.2.2/255.255.0.0; ospf

) and enter:

priority

priority

can be 0 (the router is ineligible to become the designated router) or an

integer indicating the priority level.

For example, the following command assigns a priority of 2 to interface 2.2.2.2:

ospf/2.2.2.2#

priority 2

ospf/2.2.2.2#

1 2 ... 190 191 192 193 194 195 196 197 198 199 200 ... 361 362
