When the system is powered on, the Barricade builds its own routing
database according to previous static routing entries, and/or collects
routing information from adjacent routers through RIP 2 protocol. RIP-1
is generally supported by all routers, but RIP 2 carries more information
which allows the Barricade to make better choices on the most appropriate
path to a remote network.
