Configuring Dynamic Routing

Routing Information Protocol (RIP) is an Interior Gateway Protocol (IGP) that is

commonly used in internal networks. It allows the router to exchange its routing

information automatically with other routers, and allows it to dynamically adjust its

routing tables and adapt to changes in the network.

Dynamic Routing enables the CVR100W to automatically adjust to physical

changes in the network’s layout and exchange routing tables with the other

routers.

The router determines the network packets’ route based on the fewest number of

hops between the source and the destination.

NOTE

RIP is disabled by default on the CVR100W.

To configure dynamic routing:

STEP 1

Choose

Networking

>

Routing

.

STEP

2

In the

Dynamic Routing

area, configure the following settings:

Gateway

(Recommended) Click this radio button to set the

CVR100W to act as a gateway.

Keep this default setting if the CVR100W is hosting

your network’s connection to the Internet.

Router

Click this radio button to set the CVR100W to act as a

router.

Select this option if the CVR100W is on a network with

other routers.

Enabling the Router mode disables NAT (Network

Address Translation) on the CVR100W.

RIP

Check

Enable

to enable RIP. This allows the CVR100W

to use RIP to route traffic.

Configuring Static Routing

You can configure static routes to direct packets to the destination network. A

static route is a pre-determined pathway that a packet must travel to reach a

specific host or network.

Some ISPs require static routes to build your routing table instead of using

dynamic routing protocols. Static routes do not require CPU resources to

exchange routing information with a peer router.

You can also use static routes to reach peer routers that do not support dynamic

routing protocols. Static routes can be used together with dynamic routes.

!

CAUTION

Be careful not to introduce routing loops in your network.

To configure static routing:

STEP 1

Choose

Networking

>

Routing

.

STEP

2

In the

Static Routing

area, choose a route entry from the

Route Entries

drop-

down menu.

To delete the route entry, click

Delete

This Entry

.

STEP

3

Configure the following settings for the selected route entry:

RIP Send Packet

Version

Select the RIP Send Packet Version (

RIPv1

or

RIPv2

).

The version of RIP used to send routing updates to

other routers on the network depends on the

configuration settings of the other routers.

It is best to check with your network administrator to

see which version of RIP is supported on your

network.

RIPv2 is backward compatible with RIPv1.

RIP Recv Packet

Version

Choose the RIP Receive Packet Version.

Configuring Dynamic DNS

The routing table displays the following information:

Configuring Dynamic DNS

Dynamic DNS (DDNS) is an Internet service that allows routers with varying public

IP addresses to be located using Internet domain names. To use DDNS, you must

set up an account with a DDNS provider, such as oray.org or 3322.org.

The router notifies dynamic DNS servers of changes in the WAN IP address so that

any public services on your network can be accessed by using the domain name.

To configure DDNS:

STEP 1

Choose

Networking

>

Dynamic DNS

.

STEP

2

From the

DDNS Service

drop-down menu, choose

Disable

to disable this service

or choose the DDNS service to use.

STEP

3

If you do not have a DDNS account, click the URL of the service to visit the

selected DDNS service's website so that you can create an account.

STEP

4

Configure the following information:

Destination LAN IP

(IPv4) IP address of the destination LAN.

Subnet Mask

(IPv4) Subnet mask of the destination network.

Gateway

(IPv4) IP address of the gateway used for this route.

Interface

(IPv4) Physical network interface through which this

route is accessible.

Destination

(IPv6) IP address of the destination LAN.

Next Hop

(IPv6) IP address of the gateway/router through which

the destination host/network can be reached.

Interface

(IPv6) Physical network interface through which this

route is accessible.

Username

Enter the username of the DDNS account.
