I am having trouble figuring out how I should configure a physical interface and a carp virtual interface where the carp IP will serve as a default route for hosts on the network and also hold some aliases for server re-directs. From what I have seen the routes built at startup "home" the route for the network on the interface that is configured with the actual network mask so:
>/etc/hostname.em0 >inet A.B.C.14 255.255.255.240 A.B.C.15 rdomain 2 > >/etc/hostname.carp0 >vhid 9 pass XXXXXXXX rdomain 2 >inet A.B.C.1 255.255.255.255 A.B.C.15 rdomain 2 >inet alias A.B.C.3 255.255.255.255 A.B.C.15 rdomain 2 >inet alias A.B.C.4 255.255.255.255 A.B.C.15 rdomain 2 Will put the A.B.C.0/28 entry in table 2 to: >A.B.C.0/28 link#1 UC 0 0 - 4 em0 Changing the masks so carp0 has the open mask on its first ip and em0 is all 1s yields: >A.B.C.0/28 link#9 UC 0 0 - 4 carp0 Is it better for that to be on carp0 instead of em0, given that carp0 will be the router for that network?
