Define an IP Default Gateway
An IP default gateway is an IP router that is resident on the local IP
network that this router is connected to and is used to route IP frames
for destination networks that do not exist in the routing tables. When
an IP frame is received that is destined for a network that is not listed
in the routing tables of the router, the router will send the IP frame to
the default gateway. If the device originating the IP frame is on the
same local LAN as the router, the router will then send an ICMP
redirect message to the originating device. Any future IP frames for
that destination network will then be sent to the default gateway instead
of the router.
A default gateway may be configured if there are a large number of
routes that will pass through another router to a larger network. An
example of this would be a router that is used to connect to the
Internet. All of the routers on the local LAN would have the Internet
access router as the default gateway. The routers would route
information within the internal network and any IP frames that are
destined for the Internet would be routed to the default gateway.

Ä Default Gateway
The IP address of the default gateway consists of 4
octets and is represented by 4 fields separated by
periods (“.”), where each field is specified by a
decimal number (e.g. 199.169.1.10). Each decimal
number must be less than or equal to 255, that is
the maximum value of each 8-bit field.
A configured Default Gateway will override a
default route learned from RIP.
Configuration: The Default Gateway may be located across the
WAN connection.
