Folks,

While it is true that you cannot ping unnumbered serial interfaces,
fortunately, the SNMP designers have designed things so that it *IS*
possible to query unnumbered interfaces using SNMP.  The SNMP packets are
aimed at any IP address of the router, and refer to interface numbers
(i.e., the 1st, or 2nd, interface).  Another effect of this is that
you can use SNMP to query about non-IP speaking interfaces.

PS: It is not possible to netboot a router over an unnumbered serial line.
