Settings required for the L2TP tunnel configuration:
Enter the IP address assigned as the local tunnel end point address, not the
interface IP address. This IP is used as the tunnel source IP address. If this
parameter is not specified, the source IP address is chosen automatically
based on the tunnel peer IP address. This parameter is applicable when
establishing the tunnel and responding to incoming tunnel create requests.
Set the maximum transmission unit (MTU). The MTU is the size (in bytes) of the
largest protocol data unit the layer can pass between tunnel peers. Define a
MTU between 128 - 1,460 bytes. The default setting is 1,460. A larger MTU
means processing fewer packets for the same amount of data.
Select the L2TPv3 tunnel policy. The policy consists of user defined values for
protocol specific parameters which can be used with different tunnels. If none
is available a new policy can be created or an existing one can be modified. For
more information, refer to
Provide the tunnel specific hostname used by this tunnel. This is the host name
advertised in tunnel establishment messages.
Specify the router ID sent in tunnel establishment messages with a potential
peer device.
