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.

ÄDefault 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
A configured Default Gateway will override a default route learned from RIP.
Configuration: The Default Gateway may be located across the WAN connection.
