The default route has both the destination and mask configured as 0.0.0.0. If
the destination IP address of a packet does not match any entry in the routing
table, the router will select the default route to forward the packet

Configuring RIP
RIP is a Distance-Vector (D-V) routing protocol. It advertises routing information in
User Datagram Protocol (UDP) datagrams.
User Datagram Protocol (UDP) datagrams.
RIP uses a hop count, or a routing cost, as the metric to a destination. The hop
count from a router to a directly connected network is 0, and that to a network
which can be reached through another router is 1, and so on. To restrict the
convergence time, RIP prescribes that a cost is an integer ranging from 0 and 15. A
hop count equal to or exceeding 16 is defined as infinite; that is, the destination
network or the host is unreachable. To improve performance and avoid routing
loops, RIP supports split horizon. Besides, RIP can redistribute routes from other
routing protocols.
