You are correct Phil, this is also what I found. RIP does support poison reverse.
The text book was incomplete. Also on page 488 of "All in one CCIE Study Guide", second edition they say that the RIP holdddown timer is not used. I gess I should check this other too. Can't trust the books!

Cisco DOES support poison reverse in their IP RIP implementations. They set the metric to infinity or 16. I have verifified this by lab using a sniffer. See : http://www.cisco.com/univercd/cc/td/doc/product/aggr/vpn5000/5000mgr/mgrref/ iproutg.htm#xtocid113217 or try www.cisco.com and search for 'poison reverse' Phil. --- Pierre-Alex GUANEL wrote: > Cisco does not seem to support poison reverse for > RIP and RIP version 2. > > Do you know network vendors who do? > > Pierre-Alex [EMAIL PROTECTED] __________________________________________________ Do You Yahoo!?
