There are certain MACs that can move between different interfaces,ДЇor example, primary role change in the Virtual Router Redundancy Protocol Interface, then the local interface is considered to be looped and MAC moves from LSI to local interface or from local interface to local Moves between different interfaces is learned. Interface is null) starts moving, then the statistics of such MAC If the MAC that has no base interface information( Base Learning Have a base interface and hence the statistical approach is used. If the MAC has notД«een learned for over 300 seconds at an interface, then it does not Statistical approach algorithmвЂ“ This is the secondaryДЄpproach used to disable the looped interface. Then the local interface is considered to be looped and has to be If the MAC move happens frequently between the local interfaceДЄnd the LSI interface while the base interface of the MAC is an LSI, Stable and this interface is considered as the base interface of the If the MAC stays at the interface it was first learned forДЈ00 seconds, then the interface-MAC association is considered to be This is the primary approach used to disable the looped interface.Д«ase interface information is maintained for every MAC in the routing The following two approaches can be used to disable the interfaceД«ase learning interface (base IFL) approach algorithm. To rectify the problem by disabling such an interface in the network. These loops in the VPLS network causeДЇrequent MAC moves between different interfaces which can be used Specified period of time over which the MAC address moveД¬onfiguration errors at the network can force traffic into neverД®nding circular paths or loops. Number of times a MAC address move occurs You can configure the router to report a MAC address move based (LSIs), or within a different unit of the same physical interfaceДЄnd if this behavior occurs frequently, then it is considered a MAC Local interfaces (Gigabit Ethernet interfaces) or label switched Interfaces (MAC) address appears on a different physical interface, for example, (VPLS) deployment, when a previously learned media access control OS 14.2, you can configure the router to prevent a loop in a VPLS
