IP Subnet Mask: Enter the subnet mask for this destination.

Gateway IP Address: Enter the IP address of the gateway. A gateway does the actual forwarding of the packets. Enter the gateway’s IP address in the field or select which PVC you wish to act as a gateway.

The gateway is an immediate neighbor of your ADSL Router that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your Router; over Internet (WAN), the gateway must be the IP address of one of the remote nodes.

Metric: Metric represents the “cost” of transmission for routing purposes. IP Routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Enter a number that approximates the cost for this link. The number need not to be precise, but it must between 1 and 15. In practice, 2 or 3 is usually a good number.

Announced in RIP: This parameter determines if the ADSL router includes the router to this remote node in its RIP broadcasts. If you choose Yes, the router in this remote node will be propagated to other hosts through RIP broadcasts. If you choose No, this route is kept private and is not included in the RIP broadcasts.

When you are done making changes, click on SAVE to save your changes, DELETE to delete the rule with the parameters you set, BACK to return to the previous screen or CANCEL to exit without saving.

￿3.10.3.2 Dynamic Routing

Go to Interface Setup -> LAN to select the Dynamic Route from RIP1, RIP2-B, and RIP2-M.

Explaining RIP Setup

Routing Information Protocol (RIP) allows a router to exchange routing information with other routers. The RIP Direction field controls how RIP packets are allowed to enter and leave the router. Selecting Both means the router will broadcast its routing table and incorporate the RIP information that it receives. Selecting In Only means the router will only accept RIP packets received, not send RIP packets. Selecting Out Only means the router will only send RIP packets, not accept any RIP packets received. Selecting None means the router will not send any RIP packets nor will it accept any RIP packets received.

The Dynamic Route field controls the format and the broadcasting method of RIP packets that the router sends. It recognizes both formats when receiving packets.
