ip ospf <instance-tag> area

Description

Runs the OSPF protocol on the interface with the configured IPv4 address for the area specified. The interfaces which have an IP address configured in this network or in a subset of this network, will participate in the OSPF protocol.

For moving an interface to a new area, unmap the existing area and then associate a new area to the interface.

The no form of this command disables OSPF on the interface. The interfaces which have an IP address configured in this network or in a subset of this network, will stop participating in the OSPF protocol.
