Nettet23. nov. 2013 · However, some routing protocols have specific features to avoide loops such as EIGRP, as it uses Advertised distance and Feasible distance to prevent loops. OSPF however, is a protocol itself which doesnt provide loop prevention mecahanism by the characterstics of the link state routing protocols, but it relies on the LSA types and … NettetTo stop a futile neighbor state loop, you can either manually deactivate the interface or suspend the OSPF interface within OMPROUTE so that OMPROUTE will stop attempting to form the adjacency over the interface. If the OSPF interface is suspended, any active sessions using static routes over the interface will not be disrupted.
