Configured router dead interval for this interface. |
Network Type |
Set the network type for this interface, point-to-point or broadcast. |
Designated Router |
IP address of the router that has been elected DR on this interface. |
Backup Desig. Rtr |
IP address of the router that has been elected BDR on this interface. |
