The carp
interface is a pseudo-device which implements and controls
the CARP protocol. carp
allows multiple hosts on the same local
network to share a set of IP addresses. Its primary purpose is to
ensure that these addresses are always available, but in some
configurations carp
can also provide load balancing functionality.
