•

MAC Address (IPv4 only):

The MAC address of a client.

•

Client Lease Time:

The amount of time that a network user can remain

connected to the router with a dynamic IP address.

•

Delete (IPv4 only):

Click the icon to delete the lease and disconnect the

client.

Router Advertisement (IPv6)

Use the

DHCP > Router Advertisement

page to enable the

RADVD (Router

Advertisement Daemon)

for IPv6 auto-configuration and routing. When this

feature is enabled, messages are sent by the router periodically and in response

to solicitations. A host uses the information to learn the prefixes and parameters

for the local network. Disabling this feature effectively disables auto-configuration,

requiring manual configuration of the IPv6 address, subnet prefix, and default

gateway on each device.

This page is available if you enabled Dual-Stack IP on the

Setup > Network

page.

If you did not do so, a message appears when you try to open this page. After

reading the message, you can click

OK

to configure the network settings, or click

Cancel

simply to close the message.

To open this page:

Click

Enable Router Advertisement:

To enable this feature, check the box, and

then complete the other fields on the page. To disable this feature, uncheck

the box.

•

Advertise Mode:

Choose one of the following options:

-

Unsolicited Multicast:

Select this option to send Router Advertisement

messages to all interfaces in the multicast group. This option is the

default setting. If you choose this option, also enter the

Interval

, which is the interval at which Router Advertisement messages

are sent. Enter any value between 10 and 1800 seconds. The default is

30 seconds.

-

Unicast only:

Select this option to send Router Advertisement

messages only to well-known IPv6 addresses.

RA Flags:

Choose whether or not hosts can use DHCPv6 to obtain

addresses and other information. The options are described below.

-

Enabling the Managed flag only:

Check the

Managed

box if you want

hosts to use an administered /stateful configuration protocol (DHCPv6)

to obtain stateful addresses and other information through DHCPv6.

-

Enabling the Other flag only:

Check the

Other

box if you want hosts to

use an administered/stateful configuration protocol (DHCPv6) to obtain

other, non-address information, such as DNS server addresses.

-

Enabling both flags:

Check both boxes if you want hosts to obtain

addresses and other information through DHCPv6.

-

Disabling both flags:

Uncheck both boxes if you want hosts to obtain

addresses and other information through router advertisements and not

DHCPv6.

•

Router Preference:

Choose

High, Medium

, or

Low

. This preference metric

is useful in a network topology in which multi-homed hosts have access to

multiple routers. This metric helps a host to choose an appropriate router. If

two routers are reachable, the one with the higher preference will be

chosen. These values are ignored by hosts that do not implement router

preference. The default setting is High.

•

MTU:

Enter the size of the largest packet that can be sent over the network.

The

MTU (Maximum Transmission Unit)

is used in Router Advertisement

messages to ensure that all nodes on the network use the same MTU value

when the LAN MTU is not well-known. The default setting is 1500 bytes,

which is the standard value for Ethernet networks. For PPPoE connections,

the standard is 1492 bytes. Unless your ISP requires a different setting, this

setting should not be changed.

•

Router Lifetime:

Enter the time in seconds that the Router Advertisement

messages will exist on the route. The default is 3600 seconds.

diagnostic tools, and to perform tasks such as firmware upgrades, backups, and

reboots. Refer to these topics:

Setting Up Dual WAN and Multi-WAN Connections

Use the

System Management > Dual WAN

page (or

Multi-WAN

on RV016) to

configure the settings for your Internet connections, if you are using more than one

WAN interface.

To open this page:

Click

System Management > Dual WAN (or Multi-WAN on

RV016)

in the navigation tree.

Mode - Cisco RV042, RV042G, and RV082

You can configure up to two Internet connections by using the Internet port and the

DMZ/Internet port. You can choose one of the following modes to manage your

WAN connections:

•

Smart Link Backup:

Choose this mode to ensure continuous connectivity. If

the primary WAN connection is unavailable, the backup WAN connection is

used.

•

Load Balance:

Choose this mode to use both Internet connections

simultaneously to increase the available bandwidth. The router balances the

traffic between the two interfaces in a weighted round robin fashion.

NOTE:

DNS queries are not subject to load balancing.

Mode - Cisco RV016

You can configure up to seven Internet connections by using the two Internet ports

and the five dual-function ports. You can choose one of the following modes to

manage your WAN connections:

•

Intelligent Balancer (Auto Mode):

Select this option to balance traffic

between all interfaces to increase the available bandwidth. The router

balances the traffic between the interfaces in a weighted round robin

fashion.

•

IP Group (By Users):

Select this option to group traffic on each WAN

interface by priority levels or classes of service (CoS). With this feature, you

can ensure bandwidth and higher priority for the specified services and

users. All traffic that is not added to the IP Group uses Intelligent Balancer

mode. To specify the services and users, click the

Edit

icon for the WAN

interface and then add protocol binding entries for each service, IP address,

or range of IP addresses.

NOTE:

The Router reserves at least one WAN port for non-IP Group users,

so WAN1 will always be set to Intelligent Balancer (Auto Mode). Protocol

binding is not available for WAN1.
