Configuring Intra-Site Automatic Tunnel Addressing Protocol (ISATAP)
Tunnels
Intra-site automatic tunnel addressing protocol (ISATAP) is a method to transmit
IPv6 packets between dual-stack nodes over an IPv4 network. The Cisco
RV120W is one endpoint (a node) for the tunnel. You must also set a local endpoint,
as well as the ISATAP Subnet Prefix that defines the logical ISATAP subnet to
configure a tunnel.
To add an ISATAP tunnel:
Choose Networking > IPv6 > Tunneling.
In the ISATAP Tunnel Table, click Add.
Enter the tunnel name.
Choose the local endpoint address, or the endpoint address for the tunnel that
starts with the Cisco RV120W. The endpoint can be the LAN interface (if the LAN
is configured as an IPv4 network), or another LAN IPv4 address.
If you chose Other IP in Step 4, enter the IPv4 address of the endpoint.
Enter the ISATAP subnet prefix. This is the 64-bit subnet prefix that is assigned to
the logical ISATAP subnet for this intranet. This can be obtained from your ISP or
internet registry, or derived from RFC 4193.
Click Save.
To modify the settings of an ISATAP tunnel:
Choose Networking > IPv6 > Tunneling.
Check the check boxes for the tunnels you want to modify.
Click Edit, make the changes, and click Save.
