Figure 5-92 Adding a new Tunnel Interface
6. Tabulated below is the table which explains the parameters for creating a new tunnel:
Parameter Description
Name Represents the name of the tunnel interface. Type a name for the tunnel interface.
Encapsulation The device supports two types of network tunnels:
Method
• ipip: A tunnelling protocol that allow only IP traffic over the tunnel.
• gre (Generic Routing Encapsulation): A tunneling protocol that allows
encapsulation of a wide variety of packet types in Internet Protocol (IP)
packets, thereby creating a virtual point-to-point link.
Select the tunnel type as either ipip or gre.
Virtual IP Address Represents the virtual IP address of the tunnel interface. Enter the virtual IP address of
the tunnel interface.
Local IP Address Represents the IP address of the tunnel entry point. Select the IP address of the tunnel
entry point from the available list of addresses.
Remote IP Address Represents the IP address of the tunnel exit point. Type the IP address of the tunnel
exit point. Please note that the Remote IP address should be routable.
TTL TTL stands for Time to Live. This parameter enables to configure a fixed TTL value on
the tunneled packets. The TTL value can be configured in the range 0 to 255. By
default, the TTL value is set to 0 meaning that tunneled packets inherit the TTL value from
the IP packet originated by the sender.
Entry Status By using this parameter, a tunnel interface can be enabled or disabled. By default, it is
enabled. To disable, select Disable.
7. Next, click Add.
:
• A maximum of 16 tunnels can be created on a device.
