Kenneth,

Last I checked, HSRP uses priorities to determine
active/standby routers and doesn't have any features
that look at routing table entries to adjust the
priority. Would be a nice knob though - similar to
tracking interfaces.

One way to load balance w/HSRP on the LAN side would
be to set up MHSRP and point half the users to one
groups Virtual IP address and the other half of the
users to the other group.

HTH, Erick
