That similar to my understanding, I should have explained more, I am creating i
nteresting traffic on the client before during and after the connection is down
It just that no route ever takes over from the one that's down similar to the e
xample as shown on page 524 in Solie unless I load balance and that's not the p
oint
I pulled that lab apart so I will recreate this later today and try downing the
port (as suggested)on the cat rather than using ipx down or taking off the net
work addressing.
Anyone else had similar issues with snapsot routing,
Regards
Mark

Subject: RE: Backup using snapshot routing
Mark,
The way i understand it is Snapshot routing by itself is not a backup
mechanism,so when the link fails if u have interesting traffic (in form of
Ping or actual traffic) the link would come up.Snapshot routing is actually
used to ensure that DV protocols dont keep the link up due to periodic route
updates or other broadcasts. So try pinging or claering the routing table on
the client.
HTH. Anyone care to add or correct me.Let me know.
Good luck,
kasturi.
