| Subject: | [c-nsp] ARP Timeout - IP address takeover | Actions... |

PS> Date: Fri, 21 Jan 2005 04:46:40 -0500 PS> From: Paul Stewart <pauls at nexicom.net>
PS> Our mail administrator is implementing a small mail cluster solution PS> that involves using IP takeover techniques in case of failure. So, at PS> one moment an IP could belong to one MAC address but if a box fails that PS> IP could showup with a different MAC within seconds....
Some of us use BGP, advertise a /32 internally, and crank down the timers. i.e., consider failing over at a higher level. Also consider lower-level failover with MAC address takeover methods such as HSRP and VRRP.
Not advocating any particular method for your situation... just tossing out some general suggestions to consider.
