Chapter 3 Configuring Open Shortest Path First (OSPF)

Configuring OSPF on a CSS IP Interface

The hello interval is the length of time, in seconds, between hello packets that the interface sends to its neighbor routers. The hello interval must be the same value for all routers attached to a common network. Use the ospf hello command to set the hello interval for the IP interface. Enter an integer from 1 to 65535. The default is 10 seconds.

To set a hello interval of 25 seconds, enter:

(config-circuit-ip[VLAN6-3.1.2.2])# ospf hello 25

To reset the hello interval to the default value of 10 seconds, enter:

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

Setting the Password

All OSPF protocol exchanges can be authenticated to ensure only known, trusted routers participate in routing updates. The OSPF password is used for authentication of all OSPF protocol exchanges.

Use the ospf password command to set the password for an interface. This password must be the same for all routers attached to a common network. Enter a quoted text string with a maximum of eight characters.

For example, to set the password of quota, enter:

(config-circuit-ip[VLAN6-3.1.2.2])# ospf password “quota”

To remove the OSPF password from the interface, enter:

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

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).
