must ... find... coffee .... just catching back up as dc awakens. the default gateways used by the pc's are the virtual router addresses, a different one for each (i.e. pc1 uses virtual router 1 and pc2 uses virtual router 2). the pc arp caches correctly reflect the virtual mac address (cisco generated 00000c...)which are different than the router interfaces bia's. the virtual macs do move and the different interfaces do seem to stop and start their role as the active interface.
looking over the traces last nite didn't yield much more. i have a couple things to try and i did find a tac article that holds some hope using standby use-bia. we'll see. thanks for all your thoughts and help. i'll get this to work or i'll revert to plan b, 2 tin cans and ... ----- Original Message ----- From: Priscilla Oppenheimer Date: Thursday, March 6, 2003 5:14 pm Subject: RE: it started out as a really good idea ...
