Need help on DDR if workable

Hi i need some advice on proposing

a back up route for a CAT6K ( the CAT6K in HSRP). One of the CAT6K port is non switchport and connected to SiteB through metroethernet.(see attached diagram) The routes going to 172.16.2.X and 172.16.3.X goes through the metroE and the 2600 has a network behind it that sees the routes to 172.16.2.X and 172.16.3.X through the CAT6K VIP IP (192.168.1.VIP)

Question is since one of the port in 2600 has an ip of and part of VLAN5, if the MetroE fails, what would be the best DDR option to use to have the ISDN kick-in to dial to site B

I was thinkin of floating static routes for the CAT6K

e.g. CAT6K routing

ip route 172.16.2.X

ip route 172.16.3.X

ip route 172.16.2.X 200

ip route 172.16.3.X 200

2600 routing (one of the ethernet interface have an ip of

ip route 172.16.2.X 192.168.1.VIP

ip route 172.16.3.X 192.168.1.VIP

ip route 172.16.2.X Dialer1 {SITE B loopback ip?} 200

ip route 172.16.2.X Dialer1 {SITE B loopback ip?} 200

Is there a possibility that the routes will just throw back and forth between the 2600 ethernet and CAT6K VIP ip when the metroE fails? Any suggestions on the interesting traffic for the dialer watch?

For the primary route cofiguring dynamic routing protocol would be a best option so that the changes will be automatically detected.Configuring floating routes for Backup is the right way to do.
