OSPF/4/CONFLICT_IP_ADDRESS: OSPF interface IP address conflict is detected on intra-area. (ProcessId=[USHORT], RouterId=[IPADDR], AreaId=[IPADDR], InterfaceName=[STRING], IpAddr=[IPADDR], AdvertiseRouterId=[IPADDR])


Conflicting interface addresses were detected in an OSPF area.


Parameter Name Parameter Meaning
ProcessId Indicates the ID of a process.
RouterId Indicates the router ID of a device.
AreaId Indicates the ID of an area.
InterfaceName Indicates the name of an interface.
IpAddr Indicates an IP address.
AdvertiseRouterId Indicates the ID of the advertising router.

Possible Causes

Two indirectly connected routers in an area were configured with the same IP address, and one of the routers functioned as the DR and advertised network LSAs, causing constant route flapping.


  1. Modify the IP addresses of the routers to ensure that each router in the area is configured with a unique IP address.
