After you define an OSPF area, you can assign one or more networks to it. The OSPF protocol will run on the interface with the configured IPv4 address. The interfaces which have an IP address configured in this network or in a subset of this network, will participate in the OSPF protocol.
Prerequisites
You must be in the interface configuration context, as indicated by the
switch(config-if)# prompt.
Procedure
-
Set an OSPF network for the area using the following command. For command details, see
ip ospf <instance-tag> area.
ip ospf
<instance-tag> area
<area-id>
For example, use the following command to assign interface 1/1/1 to OSPF area 1. The area can alternately be entered as an IPv4 address.
switch(config)# interface 1/1/1
switch(config-if)# ip ospf 1 area 1
-
Optionally, you can disable OSPF on the interface using the following command. For command details, see
ip ospf shutdown.
ip ospf shutdown
switch(config)# interface 1/1/1
switch(config-if)# ip ospf shutdown
