To enable OSPF on an interface and assign the interface to an area, use the set protocols ospf4 area interface vif address command in L2/L3 configuration mode. The interface will send and accept OSPF LSAs (link-state advertisements).

set protocols ospf4 vrf vrf-name area area-id interface interface-name vif vif-name address ip-address



Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>].

Note that: The configuration is in the default VRF if not explicitly bound to any VRF.

area-idOSPF area identifier. Use the dotted decimal notation. For example, use for area 0.
