Paul,
In the past I had a scanerio where this was the problem, I came up
with the use of the "no ip classless" command.
The key here is that in summarizing the /19 to a longer mask. This with the
"no ip classless" should allow for packets to
be routed through the network, however when arriving on the locally sourced
router, the packet should remain classfull
and be routed to the correct segment versus using the summary route. Of
course there are only few circumstances where
this configuration will make sense, a lab enviroment is major one of them
that comes to mind.
Here's a pretty good link. I know a couple of years ago there was a pretty
active on the list about using the "ip classless"
command. Check there as well if interested.
