The following running-configuration example shows the results of entering the
commands in Table 3-2.
!************************** CIRCUIT **************************
circuit VLAN6
ip address 3.1.2.2 255.255.255.0
ospf
ospf area 1.1.1.1
ospf priority 0
3. Create the IP interface to the circuit. To create an IP address of 3.1.2.2 with
a subnet mask of /24, enter:
(config-circuit[VLAN6])# ip address 3.1.2.2/24
Create ip interface <3.1.2.2>, [y/n]: y
4. Configure the IP interface as an OSPF interface. Enter:
(config-circuit-ip[VLAN6-3.1.2.2])# ospf
5. (Optional) If the globally configured area is other than the backbone area,
enter the configured area ID. In this example, the globally configured area
ID is 1.1.1.1.
(config-circuit-ip[VLAN6-3.1.2.2]) ospf area 1.1.1.1
6. (Optional) With a default setting of 1, the CSS is set to a priority that allows
it to become the designated router. If you do not want the CSS to become
the designated router, you can change its priority or disable it from
eligibility. For example, if you want the CSS to be ineligible to become a
designated router, enter:
(config-circuit-ip[VLAN6-3.1.2.2])# ospf priority 0
For more information on designated routers, see the “Setting the Priority of
the CSS” section.
7. Enable OSPF on the interface. Enter:
(config-circuit-ip[VLAN6-3.1.2.2])# ospf enable
