Define the following Settings required for the L2TP tunnel configuration:
Refer to the Peer table to review the configurations of the peers available for tunnel connection.
Select + Add Row to populate the table with a maximum of two peer configurations.
Local IP Address 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.
MTU 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 from
128 - 1,460 bytes. The default setting is 1,460. A larger MTU means processing fewer packets for
the same amount of data.
Use Tunnel Policy 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 Configuring Captive
Portal Policies on page 9-569.
Local Hostname Provide the tunnel specific hostname used by this tunnel. This is the hostname advertised in tunnel
establishment messages.
Local Router ID Specify the router ID sent in tunnel establishment messages with a potential peer device.
Establishment Criteria Specify the establishment criteria for creating a tunnel. The tunnel is only created if this device is
one of the following:
•
vrrp-master
•
cluster-master
•
rf-domain-manager
The tunnel is always created if Always is selected. This indicates that the device need not be any
one of the above three (3) to establish a tunnel.
VRRP Group Set the VRRP group value. This is only applicable if the Establishment Criteria specifies vrrp-master.
Critical Resource This table lists the critical resources defined for this system. The tunnel is created and maintained
if the critical resources are available. The tunnel is brought down if any one of the defined critical
resource goes down or is unreachable.
