ICMP messages.  The ICMP extension defined herein can be used
identify any combination of the following: the IP interface upon
which a datagram arrived, the sub-IP component of an IP interface
upon which a datagram arrived, the IP interface through which the
datagram would have been for forwarded had it been forwardable, the
IP next hop to which the datagram would have been forwarded.

Devices can use this ICMP extension to identify interfaces and their

these extensions to identify both numbered and unnumbered interfaces.
