Yes, with some caution. The information that this rule applies to has to be just route-to-host communication related to the fail-over address, and not router-to-router. So, for example, if you use RIP to give routes to your hosts, you can and should transmit those packets from the virtual IP address even after failing over (so that the routes on the hosts don't just time out), and you should respond to queries used by hosts to seed their tables at boot time, but you generally should *not* respond to SNMP requests or advertisements from other routers. It's a weird state. -- James Carlson, Solaris Networking <[EMAIL PROTECTED]> Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ networking-discuss mailing list [email protected]
