Set Up an IPv6 6rd Tunnel Connection
The 6rd protocol makes it possible to deploy IPv6 to sites using a service provider’s IPv4
network. 6rd uses the service provider’s own IPv6 address prefix. This limits the operational
domain of 6rd to the service provider’s network and is under direct control of the service
provider. The IPv6 service that is provided is equivalent to native IPv6.
The 6rd mechanism relies on an algorithmic mapping between the IPv6 and IPv4 addresses
that are assigned for use within the service provider’s network. This mapping allows for
automatic determination of IPv4 tunnel endpoints from IPv6 prefixes, enabling stateless
operation of 6rd.
To set up an IPv6 6rd tunnel connection:
1. Launch a web browser from a computer or WiFi device that is connected to the network.
2. Type http://www.routerlogin.net.
A login window opens.
3. Enter the modem router user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
4. Click the OK button.
The BASIC Home page displays.
5. Select ADVANCED > Advanced Setup > IPv6.
