This works for me:
# NB: if a carp address is the lowest IP you will get duplicate
# router-id's - maybe ospfd should ignore CARP interfaces when selecting
# the host id?
router-id 1.2.3.4
area 0.0.0.0 {
interface gif0 { } # link to another site
interface gif1 { } # link to another site
# ...
interface vr1 { } # link to CARP peer
interface carp1 { passive }
interface carp2 { passive }
interface carp3 { passive }
}
OSPF doesn't work over CARP interfaces. You need to connect to the rest
of the OSPF cloud over "real" interfaces, and the CARP-connected
networks should be stub networks where your actual hosts live. And CARP
interfaces must be passive.
