Static Routing:
A router with manually configured routing tables is
known as a static router. A network administrator, with
knowledge of the internetwork topology, manually builds and
updates the routing table, programming all routes in the
routing table. Static routers can work well for small
internetworks but do not scale well to large or dynamically
changing internetworks due to their manual administration.
Static routers are not fault tolerant. The lifetime of a
manually configured static route is infinite and, therefore,
static routers do not sense and recover from downed routers
or downed links.
Dynamic Routing
A router with dynamically configured routing tables is
known as a dynamic router. Dynamic routing consists of
routing tables that are built and maintained automatically
through an ongoing communication between routers. This
communication is facilitated by a routing protocol, a series
of periodic or on-demand messages containing routing
information that is exchanged between routers. Except for
their initial configuration, dynamic routers require little
ongoing maintenance, and therefore can scale to larger
internetworks.
