Let's use the lab bellow to see how HRSP works.
See configurations;
BGP's config on ISP;
HSRP's config and here is the secret line "standby 10 track 10" hsrp is calling the object track "10"
Let's see what track 10 is doing;
Track
10 check the reachability of the router 200.14.15.0
At
this moment we have the BGP1 like active
I
put a filter to deny updated about loopback 0 of the ISP to BGP1
Then
the hrsp change the status of the BGP1 to standby
I'm still learning English, then I'm' sorry ^^
Thanks and best regards
