I agree with Jenny's comments. I've also used floating-statics for quite some time to backup frame links. I was playing around with dialer watch in the lab this weekend and it does some 'interesting' things...
For one, it seems to do away with the "interesting traffic" requirement. If the main link goes down and any of the routes in the watch list disappear, the backup link will be brought on-line. I can think of a couple of reasons why this would be attractive but by the same token, it could get rather expensive especially if you have large blocks of time where nothing is going across the line - nights/weekends - but it's still up. With the floating static method, you can utilize time-based ACLs to specify your interesting traffic thus minimizing the impact of a circuit outage over a weekend for example. Definitely try them both out in a lab though; I intend to kick the tires of dialer watch a bit more myself. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Sunday, January 13, 2002 6:31 PM To: [EMAIL PROTECTED] Subject: Re: ISDN dialer watch VS floating static routes [7:31609] I have always used floating statics to back up a frame relay network. Why? Easy - we're only just migrating to IOS 12.1. And anyway, this particular network has been using floating static routes for the last several years (since *long* before dialer watch was available) - they are flexible, suit the network topology and design, and they work. And our support mob are familiar with them, which is also a useful reason to keep using them. I'd look more closely at dialer watch for a brand new network or major redesign, but right now I personally have no good reasons for changing. YMMV.

In my scenerio, it's for an eigrp network and a single router. I've seen the following article on Cisco's website: http://www.cisco.com/warp/public/123/backup-main.html However, all things being equal, which one would you use?
