Configuring basic L2TP capabilities
Basic L2TP capability configuration includes the following tasks:
Enabling L2TP—L2TP must be enabled for L2TP configurations to take effect.
Creating an L2TP group—An L2TP group is intended to represent a group of parameters. This enables not only flexible L2TP configuration on devices, but also one-to-one and one-to-many networking applications for LACs and LNSs. An L2TP group has local significance only. However, the relevant settings of the L2TP groups on the LAC and LNS must match. For example, the local tunnel name configured on the LAC must match the tunnel peer name configured on the LNS.
Configuring the local tunnel name—The local tunnel name identifies the tunnel at the local end during tunnel negotiation between an LAC and an LNS.
To configure basic L2TP capabilities:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enable L2TP. | l2tp enable | By default, L2TP is disabled. |
3. Create an L2TP group, specify its mode, and enter its view. | l2tp-group group-number mode { lac | lns } | By default, no L2TP group is created. Specify the mode as lac on the LAC side and as lns on the LNS side. |
4. Specify the local tunnel name. | tunnel name name | Optional. By default, the device name is used. |
