Gents and Ladies,

Will all servers update their arp table, if the hsrp function propagates
gratious arp.
I've never seen this fail except on REALLY REALLY old things; Solaris 2.6 had
a problem, IIRC.
We saw firewalls of customers not accepting ARP-Replies when no ARP
whohas was sent before. We debugged ARP and found out that it refreshes
its ARP-table every 30 minutes so we waited 2 seconds before end of the
30-minutes interval and made the switch so the new MAC was there once
the firewall expired its ARP cache.
Very annoying security feature ;-)
