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.

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.
