Define an IP Default Gateway

An IP default gateway is an IP router that is resident on the local IP

network that this P850 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 P850, the P850 will send the IP frame to

the default gateway. If the device originating the IP frame is on the

same local LAN as the P850, the P850 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 P850.
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 P850s on the local LAN would have the Internet

access router as the default gateway. The P850s would route

information within the internal network and any IP frames that are

destined for the Internet would be routed to the 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.
