This is perhaps bordering on semantics, but as I understand delay (i.e.,
latency) it has no dependence on bandwidth. Delay is how long it takes
the first bit of the frame to arrive at the destination. Whereas
bandwidth determines how closely spaced the bits are and how long it
takes until the last bit of the frame arrives. So to get the best
approximation of delay, a ping should send the minimum size test data.
(E)IGRP uses static "typical" values for the transit time of a
given data link. A 10Mb Ethernet is assumed to take 1 ms and a
WAN link is assumed to take 20 ms (your geography may vary :-)
