Routers that run HSRP communicate HSRP information between each other
through HSRP hello packets. These packets are sent to the destination IP
multicast address 224.0.0.2 on User Datagram Protocol (UDP) port 1985.
IP multicast address 224.0.0.2 is a reserved multicast address that is
used to communicate to all routers. The active router sources hello
packets from its configured IP address and the HSRP virtual MAC address.
The standby router sources hellos from its configured IP address and the
burned-in MAC address (BIA). This use of source addressing is necessary
so that HSRP routers can correctly identify each other.

I believe so. It's not a trick question though is it? Is it talking
about
the hellos, which I seem to recall use the BIA.

Hello,
When the question says do not use the BIA address for HSRP. Isn't it
the
default behavior of HSRP?
Thanks in advance,
Regards,
