********* THIS OBJECT IS DEPRECATED *********
This object is used to configure whether this agent
will periodically send ICMP echo request packets to
the IP default router for this interface. Since a
networking device typically does not transmit unless
it receives a management request, and since some
autodiscovery applications work by scanning ARP
caches, this ICMP echo can be used to try to stay in
our default router's ARP cache so that we can be
discovered. This object allows the network manager
to enable or disable sending these ICMP echo
requests.
