Doubt with HSRP SW L3 with 2 ISP

[reynosoalmonte]

Hello,

I am trying to make a redundant practice. I can ping the server 172.16.0.10 from my host. 

The active switch L3 is SW-ISP-1 and the standby SW-ISP-2.

If i down the interface fa0/2 the SW-ISP-2 will be the active. Here all is very good and when the sw-isp-1 is up again, this will be standby.

Now, my doubt is: if the interface fa0/1 on my sw-isp-1 is down, i can't have any redundant link because they are in another subnet.

How can I do this?

Thanks

Hi :)

I think that it's often realized by interface tracking or object tracking.

First of all, it's recommended to try from interface tracking.

# standby (n) track fa0/1
