Use the following procedure to configure a tunnel for IPv6 VLANs to communicate through an IPv4 network. Manual tunnels are point-to-point, so you configure both source and destination addresses. You must configure both IPv6 and IPv4 addresses for both source and destination devices. The IPv6 addresses must represent the same network, for example 6666::1/96 and 6666::2/96.
From the navigation tree, double-click IPv6.
Double-click Tunnel.
Click Insert.
In the LocalAddress box, click the button and select the IPv4 address for the local VLAN.
In the RemoteAddress box, type the IPv4 address for the remote destination VLAN.
In the EncapsMethod area, select manual.
In the ID box, type a number to represent the tunnel.
In the IPv6AddressAddr box, type the IPv6 address assigned to the tunnel.
In the IPv6AddressPrefixLength box, type the number of bits to advertise in the IPv6 address.
Click Insert.
After you create the tunnel, the Local Address tab displays the IPv4 addresses associated with the tunnel.
To view the configured IPv6 Address for the tunnel, click IPv6 Address.
The following table describes the fields of the Tunnel Config tab.
Variable | Value |
---|---|
Address Type | Displays the address type for the tunnel: IPv4 for IPv6 packets encapsulated in IPv4. |
LocalAddress | Identifies the local endpoint address of the tunnel. |
RemoteAddress | Identifies the remote endpoint of the tunnel. |
EncapsMethod | Displays the tunnel mode: manual for manually configured tunnels. |
ID | Identifies the tunnel number. |
IfIndex | Displays a unique value that identifies the tunnel interface internally. The value is derived from the tunnel ID. |
