Are you guys really sure this works? I have tried CARP in the most simple setup I could. I have two machines, one network card in each machine, and I run a crossover between them. I have tried a pair of "SMC 83C170 (EPIC/100)" cards, a pair of "Intel 82557" cards, and a pair of "Compaq Netelligent 10/100 TX" cards. For the most part, when I configure everything and do a tcpdump I see the VRRPv2 announce from vhid 1 and from vhid 2... sounds like everything is working, but both boxes insist on keeping a status of MASTER on CARP0. My hostname.carp0 looks like this on both machines (with differing vhids): inet 10.0.0.1 255.255.255.0 10.0.0.255 vhid 1 pass blah What are the chances that all three sets of cards have broken/partial multicast support?
