I am needing to configure two 3750s with HSRP so that I can get a virtual IP address. 3750 #1 will have one of my internet connections and 3750 #2 will have the other. Can I use IP SLA so that if Internet connection on 3750 #1 goes down that the default route is changed to 3750 #2? I have two redundant switches behind the 3750s which each will have two connections (one to each 3750). I think that this is possible, but not 100% sure how to go about it. In theory I think that I would hook them up similar to the following...
Port 1 goes to internet connection #1
Port 2 goes to redundant switch A
Port 3 goes to redundant switch B
Port 1 goes to internet connection #2
Port 2 goes to redundant switch B
Port 3 goes to redundant switch A
Port 1 on both 3750s will hook directly to separate firewalls and have a private address. I am assuming that another port is needed on the switch for HSRP.
Thanks for any assistance that you can provide!
