VRRP
VRRP provides redundant internet gateways. Increased
availability is achieved by creating a virtual router consisting of a
group of cooperating physical routers that share a MAC and IP
address. The physical routers elect and monitor a master router to
service requests. If the master router fails, another group member
assumes its responsibilities. This implementation monitors the
spacelink (using SHM) and optionally a remote host (via pings).
This implementation also reports the VSAT as being in an up or
operational state as long as both are functioning properly.
