Chapter 3 Configuring Open Shortest Path First

Configuring OSPF on a CSS IP Interface

Setting the Poll Interval

The poll interval is the length of time, in seconds, between the transmittal of hello packets by the CSS to an assumed inactive neighbor router in a non-broadcast, multi-access network. Use the ospf poll command to set the poll interval for the interface. The poll interval should be a value that is greater than the hello time interval. Enter a number from 1 to 2,147,483,647. The default is 120 seconds.

Note The ospf poll command has no effect when you operate the CSS over a broadcast LAN (that is, an Ethernet network).

For example, to set the poll interval to 200 seconds, enter:

(config-circuit-ip[VLAN6-3.1.2.2])# ospf poll 200

To reset the poll interval to the default value of 120 seconds, enter:

(config-circuit-ip[VLAN6-3.1.2.2])# no ospf poll

Setting the Priority of the CSS

To avoid the need for each router on a LAN to talk to every router on a network that has more than two attached routers, one router is elected as the designated router. Designated routers advertise network link states for attached network segments. An LSA lists all routers that are connected to a segment.

The priority determines which router is the designated router. The router with the highest priority becomes the designated router. In case of a tie, routers use their router ID as a tie breaker.

Use the ospf priority command to set the router priority for the interface. The priority of the interface is an integer from 0 to 255. The default is 1, which is the highest router priority. A value of 0 signifies that the CSS is not eligible to become the designated router on a particular network.

If a designated router exists on the network, it remains the designated router regardless of its router priority.

To make the interface ineligible to become a designated router, enter:

(config-circuit-ip[VLAN6-3.1.2.2])# ospf priority 0
