Actually, it sounds like to me "send RIP version 1".

Subject: Re: enable/disable subnet mask service on IOS
Sounds like an ICMP Mask Request
http://www.networksorcery.com/enp/protocol/icmp/msg17.htm
RFC 950, page 11:
A gateway receiving an address mask request should return it with the
address mask field set to the 32-bit mask of the bits identifying the subnet
and network, for the subnet on which the request was received.
If the requesting host does not know its own IP address, it may leave the
source field zero; the reply should then be broadcast. However, this
approach should be avoided if at all possible, since it increases the
superfluous broadcast load on the network. Even when the replies are
broadcast, since there is only one possible address mask for a subnet, there
is no need to match requests with replies. The "Identifier" and "Sequence
Number" fields can be ignored.
