Configuring IPv6 LAN Connections

In the IPv6 mode, the LAN DHCP server is enabled by default (similar to the IPv4

mode). The DHCPv6 server assigns IPv6 addresses from configured address

pools that use the IPv6 prefix length assigned to the LAN.

To configure IPv6 LAN settings on your device, you must first set the IP mode to

one of the following modes:

•

LAN:IPv6, WAN:IPv4

•

LAN:IPv6, WAN:IPv6

•

LAN:IPv4+IPv6, WAN:IPv4

•

LAN:IPv4+IPv6, WAN:IPv4+IPv6

See

Configuring the IP Mode

for more information on how to set the IP mode.

To configure IPv6 LAN settings:

STEP 1

Choose

Networking

>

IPv6

>

IPv6 LAN Configuration

.

Enter the following information to configure the IPv6 LAN address:

STEP

or continue to configure IPv6 DHCP LAN settings.

STEP

Enter the following information to configure the DHCPv6 settings:

IPv6 Address

Enter the IPv6 address of the device.

The default IPv6 address for the gateway is fec0::1

(or FEC0:0000:0000:0000:0000:0000:0000:0001).

You can change this 128-bit IPv6 address based on

your network requirements.

IPv6 Prefix Length

Enter the IPv6 prefix length.

The IPv6 network (subnet) is identified by the initial

bits of the address called the prefix. By default, the

prefix is 64 bits long.

All hosts in the network have the identical initial bits

for their IPv6 address; you set the number of

common initial bits in the network addresses in this

field.

DHCP Status

Check to enable the DHCPv6 server.

When enabled, the device assigns an IP address

within a specified range and provides additional

information to any LAN endpoint that requests

DHCP addresses.

Domain Name

(Optional) Domain name of the DHCPv6 server.

Server Preference

Server preference level of this DHCP server. DHCP

advertise messages with the highest server

preference value to a LAN host are preferred over

other DHCP server advertise messages.

The default is 255.

Static DNS 1

IPv6 address of the primary DNS server on the ISP

IPv6 network.

Static DNS 2

IPv6 address of the secondary DNS server on the

ISP IPv6 network.

Client Lease Time

Client lease time duration (in seconds) for which

IPv6 addresses are leased to endpoints on the

LAN.

Start Address

Starting IPv6 address of the pool.

End Address

Ending IPv6 address of the pool.

IPv6 Prefix Length

Prefix length that determines the number of

common initial bits in the network addresses.

Configuring IPv6 Static Routing

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

static route is a predetermined pathway that a packet must travel to reach a

specific host or network.

Some ISPs require static routes to build a 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. Be

careful not to introduce routing loops in your network.

To create a static route:

STEP 1

Static Routing

STEP

In the list of static routes, click

Add Row

.

STEP

3

Enter this information:

Name

Route name.

Destination

IPv6 address of the destination host or network for

this route.

Prefix Length

Number of prefix bits in the IPv6 address that define

the destination subnet.

Gateway

IPv6 address of the gateway through which the

destination host or network can be reached.

Interface

Interface for the route:

LAN

,

WAN

, or

6to4

.

Metric

Priority of the route. Choose a value between 2 and 15.

If multiple routes to the same destination exist, the

route with the lowest metric is used.

Active

Check to make the route active. When you add a route

in an inactive state, it is listed in the routing table, but is

not used by the device.

Entering an inactive route is useful if the route is not

available when you add the route. When the network

becomes available, you can enable the route.

Configuring Routing (RIPng)

RIP Next Generation (RIPng) is a routing protocol based on the distance vector

(D-V) algorithm. RIPng uses UDP packets to exchange routing information through

port 521.

RIPng uses a hop count to measure the distance to a destination. The hop count is

referred to as metric, or cost. The hop count from a router to a directly connected

network is 0. The hop count between two directly connected routers is 1. When

the hop count is greater than or equal to 16, the destination network or host is

unreachable.

By default, the routing update is sent every 30 seconds. If the router receives no

routing updates from a neighbor after 180 seconds, the routes learned from the

neighbor are considered as unreachable. After another 240 seconds, if no routing

update is received, the router removes these routes from the routing table.

On your device, RIPng is disabled by default.

Configuring Tunneling

IPv6-to-IPv4 tunneling (6-to-4 tunneling) allows IPv6 packets to be transmitted

over an IPv4 network. IPv4 to IPv6 tunneling (4-to-6 tunneling) allows IPv4 packets

to be transmitted over an IPv6 network.

6 to 4 Tunneling

6-to-4 tunneling is typically used when a site or end user wants to connect to the

IPv6 Internet using the existing IPv4 network.
