Interface ID The Interface identifier that the neighbor advertises in its Hello Packets. This is a
32-bit number uniquely identifying the neighbor router’s interface. MIB-II IfIndex is
used for this identifier in some implementations.
The advantage to using the SNMP MIB-II ifIndex value is that this number
corresponds to the number that the user will see reported by SNMP.
Interface The interface to which this neighbor is attached
