Configuring an ISATAP Tunnel
Use the
Add / Edit ISATAP Tunnel Configuration
page to configure the settings for
an ISATAP tunnel. Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) is a
method to transmit IPv6 packets between dual-stack nodes over an IPv4 network.
The Cisco RV220W 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 open this page:
From the
Networking > IPv6 > 6 to 4 Tunneling
page, click
Add
or select a tunnel and then click
Edit
.
STEP 1
Enter this information:
•
Tunnel Name—
Enter a descriptive name to identify this tunnel.
•
Endpoint Address—
Enter the endpoint address for the tunnel that starts
with the Cisco RV220W. If the endpoint is on the IPv4 LAN interface, click
LAN (Local Network)
. If the endpoint is not on the local network, choose
Other IP
, and then specify the
IPv4 address
of the endpoint.
•
ISATAP Subnet Prefix—
Enter the 64-bit subnet prefix that is assigned to the
logical ISATAP subnet for this intranet. This setting can be obtained from
your ISP or Internet registry, or derived from RFC 4193.
