5.6.11 Routing (Static Routing)
If the ADSL Router is connected to more than one network, you may need to set up a static route
between them. A static route is a pre-defined pathway that network information must travel to reach a
specific host or network. You can use static routing to allow different IP domain users to access the
Internet through the ADSL Router.
The New Destination IP is the address of the remote LAN network or host to which you want to assign a
static route. Enter the IP address of the host for which you wish to create a static route here. For a
standard Class C IP domain, the network address is the first three fields of the New Destination IP, while
the last field should be 0. The Subnet Mask identifies which portion of an IP address is the network
portion, and which portion is the host portion. For a full Class C Subnet, the Subnet Mask is
255.255.255.0. The Gateway IP address should be the IP address of the gateway device that allows for
contact between the Gateway and the remote network or host. The Hop Count determines the maximum
number of steps between network nodes that data packets will travel. A node is any device on the
network (such as a router or switch)

5.6.12 Dynamic Routing
Dynamic Routing allows the ADSL Router to automatically adjust to physical changes in the network. The
ADSL Router, using the RIP protocol, determines the network packets’ route based on the fewest number
of hops between the source and the destination. The RIP protocol regularly broadcasts routing
information to other ADSL Routers on the network. The Direction determines the direction that RIP routes
will be updated. Selecting In means that the ADSL Router will only incorporate received RIP information.
Selecting Out means that the ADSL Router will only send out RIP information. Selecting both means that
the ADSL Router will incorporate received RIP information and send out updated RIP information.
The protocol is dependent upon the entire network. Most networks support Rip v1. If RIP v1 is selected,
routing data will be sent in RIP v1 format. If Rip V2 is selected, routing data will be sent in RIP v2 format
using subnet broadcasting. If Rip V1 Compatible is selected, routing data will be sent in RIP v2 format
using multicasting.
