Configuration of IPv6 Advertisement Prefixes on RV120W and RV220W

Objective

The IPv6 Router Advertisement Daemon (RADVD) broadcasts router advertisement messages and responds to router solicitations messages sent by clients. A network prefix is contained within these router advertisement messages, which is necessary for a client to automatically acquire IP addresses. Multiple prefix options can be contained inside a single router advertisement message.

This article explains about the configuration of IPv6 advertisement prefixes on the RV120W and RV220W.

Applicable Devices

• RV120W
• RV220W

Software Version

• v1.0.4.17

Configure IPv6 Advertisement prefixes

Step 1. Log in to the web configuration utility to choose Networking > IPv6 > Advertisement Prefixes. The Advertisement Prefixes page opens:

Step 2. Click Add to create a new Advertisement Prefix. The Add / Edit Advertisement Prefix Configuration window appears:

Step 3. Click the appropriate IPv6 Prefix Type radio button. The options are:

• 6to4 — The prefix is a 6to4 prefix. 6to4 allows IPv6 packets to traverse an IPv4 network.

• Global/Local/ISATAP — The prefix is a Global, Local, or ISATAP prefix.

Step 4. SLA ID is enabled only if you clicked 6to4 in the IPv6 Prefix Type field from Step 3. Enter the Site-Level Aggregation IDentifier (SLA ID) in the SLA ID field to specify the SLA ID portion of the 6to4 prefix.The SLA ID field is used by an individual user to create its own local address hierarchy and to identify subnets.  

Step 5. IPv6 Prefix is enabled only if you clicked Global/Local/ISATAP in the IPv6 Prefix Type field from Step 3. Enter the IPv6 Prefix in the IPv6 Prefix field, which specifies the network portion of an IPv6 address.

Step 6. IPv6 Prefix Length is enabled only if you clicked Global/Local/ISATAP in the IPv6 Prefix Type field from Step 3. Enter the IPv6 Prefix Length in the IPv6 Prefix Length field. It represents the number of bits in an IPv6 address that specify the network bits. Recommended value for IPv6 Prefix Length is 64.

Step 7. Enter, in seconds, how long a client can use this prefix for an address in the Prefix Lifetime field.

Step 8. Click Save at the bottom of the configuration utility to save this Advertisement Prefix. The changes will immediately show up in the next router advertisement message.
