Configuring a default route
The term "router" in this document refers to both routers and routing-capable firewalls and firewall
modules.
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. For more information, see "Configuring static routing."
• S
ome dynamic routing prot
ocols, such as OSPF and RIP, 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. For more information, see
the chapters on these routing protocols.
