• Tunnel Type—Select a tunnel type: Manual, 6 to 4 or ISATAP.
• Tunnel State (called State in the main page)—Select to enable the tunnel. If this
tunnel is later shutdown, this fact will be indicated in this field.
• Link Status SNMP Traps—Select to enable generating a trap when the link status of
a port is changed. If you are not interested in receiving such traps on specific ports (for
example, ISP only needs traps on ports connected to its infrastructure, and does not need
traps for the ports connected to the user's equipment), this feature can be disabled.
• Source (called Source Type in the main page)—Displays one of the following
options:
- Auto—Automatically selects the minimum IPv4 address from among all of its
configured IPv4 interfaces as the source address for packets sent on the tunnel
interface.
If the minimum IPv4 address is removed from the interface (removed at all or
moved to another interface), the next minimum IPv4 address is selected as the local
IPv4 address.
- IPv4 Address—Enter the IPv4 address of the interface that will be used as the source
address of the tunnel.
- Interface—Select the interface whose IPv4 address will be used as the source
address of the tunnel.
The main page has a column called Source Address. This presents the actual IP
address that was selected based on the above selection.
• Destination—(For manual tunnel only) Select one of the following options to specify
the destination address of the tunnel:
- Host Name—DNS name of the remote host.
- IPv4 Address—IPv4 address of the remote host.
• ISATAP Router Name— (For ISATAP tunnels only) Select one of the following
options to configure a global string that represents a specific automatic tunnel router
domain name.
- Use Default—This is always ISATAP.
- User Defined—Enter the router’s domain name.
STEP 4 Click Apply. The tunnel is saved to the Running Configuration file.
