OSPFv3
IFSM[interfacename]
OSPFv3 interface state machine debugging.
state (interface-event)
Current interface state state and interface event interface-event.
Current interface state:
• Down—The interface is down.
• Loopback—The interface is a loopback interface.
• Waiting—The interface is in the waiting state.
• P-To-P —The interface is connected to a P2P network or configured as one end
of a virtual link.
• Backup—The interface is the backup designated router.
• DR—The interface is the designated router.
Event that triggers an interface state change:
• InterfaceUp—The interface state is changed from Down to UP.
• WaitTimer—The wait timer expires.
• BackupSeen—Indicates whether the interface detects a BDR on the network.
The interface receives from a neighbor a hello packet declaring the neighbor is
a BDR, or declaring the neighbor is a DR.
• NeighborChange—A neighbor becomes a DR or BDR, or it is no longer a DR
or BDR. A DR/BDR re-election is required.
• LoopInd—The interface is a loopback interface.
• UnLoopInd—The interface is no longer a loopback interface.
• InterfaceDown—The interface state changes from UP to Down.
DR-Election[string]: DR
ROUTER-ID
Current DR. The string argument can take one of the following values:
• 1st—The first DR election is performed.
• 2nd—An interface state change occurs and a DR re-election is performed.
DR-Election[string]: BDR
ROUTER-ID Backup
