ASR 9000 / XR / 7.x.x / HSRP/VRRP + BFD Best Practice

[Hans Martinez]

I try to implement HSRP + BDF over 400 BVI at ASR9K, I need to know if exist a best practice about configure HSRP and BDF.

I found this link: https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/ip-addresses/command/reference/b-ip-addresses-cr-asr9000/b-ipaddr-cr-asr9k_chapter_01100.html#wp4109961970

But this document show general configuration, someone can explain me or post an example of the best practice to implement.

I dont have any links for the best poractices, but if you are looking for config smth like this should work:
