Armand,

If u look at the debugs (maybe easier in lab to use the show dialer cmd as
this generates less amount of info than debug)...gives similiar info for
troubleshooting...The show dialer cmd will show the dial reason which helps
to find why link is going UP/DOWN

When u look at the output it shows bcast as dest address

>186 bytes, outgoing interesting (list 100)

The router with Src address shown above is generating IGRP routing updates
and hence these updates. To the best of my knowledge the ways to do this is

- if u deny igrp routing updates and use static routes (may not be a option)

- USe snapshot routing as this prevents the DV protcols form sending updates
every "update interval"

I cant think of any other way ? anyone care to add ??

HTH.Are u prevented from using Snapshot ?? by the Q or Secenario.

Good luck,
kasturi.
