I'm being dense perhaps, but I think you will get a better answer if you explain the problem rather than a potential solution. I know a consultant whose mantra is tell me what, not how! ;-) Snapshot routing is a solution for reducing the number of routing updates that are sent. It works for protocols like RIP, IGRP, and RTMP that send their entire routing tables (after split horizon) frequently, like every 30 seconds for RIP, every 90 seconds for IGRP, and every 10 seconds for RTMP. Neither EIGRP nor IS-IS do this. Although EIGRP uses vectors with distance information, its updates are nonperiodic, partial, and bounded. Nonperiodic means that updates are sent only when a metric changes rather than at regular intervals. Partial means that updates include only routes that have changed, not every entry in the routing table. Bounded means that updates are sent only to affected routers. These behaviors mean that EIGRP uses very little bandwidth. However, it does send incessant Hellos (every 5 seconds) and that is probably what concerns you. I don't know IS-IS, but EIGRP learns about its neighbors with Hellos. If you want to reduce traffic and keep a DDR line from coming up just to send Hellos, you could make the DDR link a passive interface. Under the EIGRP commands, use the passive-interface dialer0 command or whatever is appropriate for your config. Then use a static route to make sure the link does come up when you need to send to the other side. You could still use EIGRP on either side but make the DDR link passive. That's one way to skin the cat anyway! ;-) ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com From: Scott Davis Reply-To: Scott Davis To: [EMAIL PROTECTED] Subject: RE: Snapshot routing for Eigrp?

RE: Snapshot routing for Eigrp? [7:56102]
I don't think you can use Link State routing protocols over snapshot because they rely on hello messages periodically (not 100% on this but pretty sure). I got it to work in a DDR EIGRP environment using floating statics, quite straight forward. -Original Message- From: Cisco Nuts [mailto:cisconuts;hotmail.com] Sent: 22 October 2002 21:20 To: [EMAIL PROTECTED] Subject: Snapshot routing for Eigrp?

Woops, That second sentence was misleading, I didn't mean I got snapshot with EIGRP to work, I used floating static's instead of Snapshot. -Original Message- From: Symon Thurlow Sent: 22 October 2002 22:05 To: [EMAIL PROTECTED] Subject: RE: Snapshot routing for Eigrp?

RE: Snapshot routing for Eigrp? [7:56102]
A minor nitpick here: EIGRP is not a link state protocol but it does use hello messages to establish and keep track of neighbors. Hello messages used by a routing protocol will complicate your DDR situation, but they are not the defining characteristic of link state protocols.
