Hi there..

Our mail administrator is implementing a small mail cluster solution
that involves  using IP takeover techniques in case of failure.  So, at
one moment an IP could belong to one MAC address but if a box fails that
IP could showup with a different MAC within seconds....

Since our core network is 100% Cisco, is there any ARP related issues
that will delay our customers in seeing the proper MAC if a mail server
failure should happen?  Or, is there any way to control the default ARP
timeout for a specific IP address?

Thanks in advance,

Paul
