An OSPF Interface is the connection between a router and one of its attached networks. An interface has state information associated with it, which is obtained from the underlying lower level protocols and the routing protocol itself. A network interface has associated a single IP address and mask (unless the network is an unnumbered point-to-point network). An interface is sometimes also referred to as a link.
To view OSPF interface statistics:
Interface Name |
Displays the IP addresses and mask defined as the virtual interface for dynamic OSPF routes. Zero config and DHCP can be used to generate route addresses, or a primary and secondary address can be manually provided. |
Interface Index |
Lists the numerical index used for the OSPF interface. This interface ID is in the hello packets establishing the OSPF network connection. |
Bandwidth |
Lists the OSPF interface bandwidth (in Kbps) in the range of 1 - 10,000,000. |
Interface Flag |
Displays the flag used to determine the interface status and how to proceed |
MTU |
Lists the OSPF interface MTU size. The MTU is the largest physical packet size (in bytes) a network can transmit. Any packets larger than the MTU are divided into smaller packets before being sent. |
OSPF Enabled |
Lists whether OSPF has been enabled for each listed interface. OSPF is disabled by default. |
UP/DOWN |
Displays whether the OSPF interface (the dynamic route) is currently up or down for each listed interface. An OSPF interface is the connection between a router and one of its attached networks. |
