Vadim, ] 2) Don't Do Any Dynamic Routing Where Only One Path Exists. Certainly I would not agree with this rule. If I have a tail router that is down, I do not want to send traffic to him, when he is not there to receive it. Rather, I would want my intermediate router to reject it right off. Furthermore, I do not want to extend nondynamic notification in my network. ------------------------ = ------------------------ Network: rtra --------+-------+ | | rtrb --------+ rtrd +--------- rtre ------- rtrf | | rtrc --------+-------+ ------------------------ = ------------------------ If rtra is down, I do not want rtre to send packets to rtrd to get to rtra, do I? Wouldn't I prefer them to be stopped ASAP? Certainly this is a debatable point. * Another situation is what happens when you renumber networks? What hapens when you've large number of downstream networks? Do you really want static routes in rtrf for all networks attached to rtrs a,b,c,d,e? What I find, is that in running a "large" network, filtered dynamic routing is far preferrable to either static leaf nodes, or unfiltered dynamic routing. I want my dynamic routing to be binary: what I should get, or nothing. -alan - - - - - - - - - - - - - - - - -
