Setting Up Advanced Routing 3 Configuring Dynamic Routing Enter the settings for dynamic routing by using Routing Information Protocol (RIP) (see the glossary for more information). Dynamic Routing for IPv4: Click the IPv4 tab, and then enter the settings described below. • Working Mode: Choose one of the following options. - Gateway: Choose this mode if the router is hosting your network's connection to the Internet. This is the default setting. - Router: Choose this mode if the router exists on a network with other routers, and another router acts as the network gateway to the Internet. In Router mode, Internet connectivity is available only if you have another router that functions as the Gateway. Since firewall protection is provided by the gateway router, disable this router's firewall. See Configuring the General Firewall Settings, page 99. • RIP: Routing Information Protocol allows a router to exchange its routing information automatically with other routers, and to dynamically adjust its routing tables as network changes occur. RIP prevents routing loops by using a hop limit. To enable this option, select Enabled. Otherwise, keep the default setting, Disabled. If you enable this feature, also configure the following settings: • Receive RIP versions: Select the RIP protocol for receiving network data: None, RIPv1, RIPv2, or Both RIP v1 and v2. RIPv1 is a class-based routing version. It does not include subnet information and therefore does not support variable length subnet masks (VLSM). RIPv1 also lacks support for router authentication, making it vulnerable to attacks. RIPv2 carries a subnet mask and supports password authentication security. • Transmit RIP versions: Select the RIP protocol for transmitting network data: None, RIPv1, RIPv2 - Broadcast, or RIPv2 - Multicast. RIPv2 - Broadcast (recommended) broadcasts data in the entire subnet. RIPv2 - Multicast sends data to multicast addresses. RIPv2 - Multicast also helps to avoid unnecessary load by multicasting routing tables to adjacent routers rather than broadcasting to the entire network.

Cisco Small Business RV0xx Series Routers Administration Guide

Configuring Dynamic Routing

Enter the settings for

dynamic routing

by using

Routing Information Protocol

(RIP)

(see the glossary for more information).

Dynamic Routing for IPv4:

Click the

IPv4

tab, and then enter the settings described below.

•

Working Mode

: Choose one of the following options.

Gateway:

Choose this mode if the router is hosting your network’s

connection to the Internet. This is the default setting.

Router:

Choose this mode if the router exists on a network with other

routers, and another router acts as the network gateway to the Internet.

In Router mode, Internet connectivity is available only if you have another

router that functions as the Gateway. Since firewall protection is

provided by the gateway router, disable this router’s firewall. See

Configuring the General Firewall Settings, page 99

•

RIP:

Routing Information Protocol allows a router to exchange its routing

information automatically with other routers, and to dynamically adjust its

routing tables as network changes occur. RIP prevents routing loops by

using a hop limit. To enable this option, select

Enabled

. Otherwise, keep the

default setting,

Disabled

. If you enable this feature, also configure the

following settings:

•

Receive RIP versions:

Select the RIP protocol for receiving network data:

None

RIPv1

RIPv2

, or

Both RIP v1 and v2

RIPv1

is a class-based routing version. It does not include subnet

information and therefore does not support variable length subnet masks

(VLSM). RIPv1 also lacks support for router authentication, making it

vulnerable to attacks.

RIPv2

carries a subnet mask and supports password

authentication security.

•

Transmit RIP versions:

Select the RIP protocol for transmitting network

data:

None

RIPv1

RIPv2 - Broadcast

, or

RIPv2

- Multicast

RIPv2 - Broadcast

(recommended) broadcasts data in the entire subnet.

RIPv2

- Multicast

sends data to multicast addresses. RIPv2 - Multicast also

helps to avoid unnecessary load by multicasting routing tables to adjacent

routers rather than broadcasting to the entire network.
