1.Click Interfaces under Configuration > Interface Configuration in the tree view.

2.Click Tunnels in the Physical column.

3.Click the drop-down window in the Create a new tunnel interface with encapsulation field and select GRE.

4.Click Apply.

5.From the Interface column on the Logical interfaces table, select tun01.

6.Enter 10.0.0.1 in the Local address text box.

7.Enter 10.0.0.2 in the Remote address text box.

8.Enter 192.68.26.65 in the Local endpoint text box.

9.Enter 192.68.26.74 in the Remote endpoint text box.

10.(Optional) Select a value from the TOS value drop-down window. Click Apply.

On GRE tunnels, it is desirable to copy or specify the TOS bits when the router encapsulates the packet. After you select the TOS feature, intermediate routers between the tunnel endpoints may take advantage of the QoS features and possibly improve the routing of important packets. By default, the TOS bits are copied from the inner IP header to the encapsulating IP header.

If the desired TOS value is not displayed in the drop-down window, select Custom Value from the menu.
