You CAN'T use one of your physical router IP addresses for the virtual.
There will be problems with the MAC addresses learned and cached by your
clients. The MAC address for the virtual router is virtual, the MAC address
for the router is physical. The correct answer would be to 1)re-address
your network (using a subnet mask other than 240), allowing more IP
addresses, 2)use DHCP with a short lease period and lease IP addresses as
needed, or 3)use ip unnumbered on the routers freeing two IP addresses and
then using one of the freed addresses for your virtual. I have tried "3" in
lab, and it worked fine. There are probably more solutions, but these were
from the top of my head.

Subject: hsrp question..a tough one for me
A question was recently posed:
Two routers-subnet for 12 hosts. Do hsrp.
naturally you assume a subnet for 14 hosts, one address each for router
a and b. then don't you need an address for the virtual ip for hsrp.
This only leaves 11 host addresses available.
My question was, "can you use one of the addresses from one of the
routers for the virtual ip address for hsrp". This would put you back
up to 12 host addresses.
Is this the right answer?
thanks,
bk
