Configuring a default route
A default route is used to forward packets that match no entry in the routing table.
Without a default route, a packet that does not match any routing entries is discarded.
A default route can be configured in either of the following ways:
• The network administrator can configure a default route with both destination and mask being
0.0.0.0. The router forwards any packet whose destination address fails to match any entry in the
routing table to the next hop of the default static route.
• Some dynamic routing protocols, such as OSPF, RIP, and IS-IS, can generate a default route. For
example, an upstream router running OSPF can generate a default route and advertise it to other
routers, which install the default route with the next hop being the upstream router.
