you shouldn't see issues but log spam. maybe you misunderstand the problem. If you have vrrp and carp on the same vlan, using the same vrrp group ID as VHID, then each virtual IP will arp for the same mac address on that vlan.
correct.
This messes up the switch's forwarding table for that particular vlan because it sees multiple entries from different ports for the same mac address.
correct. my switches seem to deal with that, wether they have special handling for that mac addr range or not i dunno. again, stress the fact that afair we have gotten zero reports about that "issue" for 10 years, it obviously means that either 1) a vast majority of switches deal with it just fine 2) people know that vhids shouldn't clash and avoid that -- Henning Brauer, hb@bsws.de, henning@openbsd.org BS Web Services GmbH, AG Hamburg HRB 128289, http://bsws.de Full-Service ISP - Secure Hosting, Mail and DNS Services Dedicated Servers, Rootservers, VMs/PVS, Application Hosting
