IP ROUTING COMMANDS

Command Mode

Interface Configuration (VLAN)

Default Setting

1

Command Usage

Set the priority to zero to prevent a router from being elected as a DR or BDR. If set to any value other than zero, the router with the highest priority will become the DR and the router with the next highest priority becomes the BDR. If two or more routers are tied with the same highest priority, the router with the higher ID will be elected.

If a DR already exists for an area when this interface comes up, the new router will accept the current DR regardless of its own priority. The DR will not change until the next time the election process is initiated.

Example

Console(config)#interface vlan 1

Console(config-if)#ip ospf priority 5

Console(config-if)#

ip ospf retransmit-interval

Use this command to specify the time between resending link-state advertisements (LSAs). Use the no form to restore the default value.
