Usage Scenario
If the PEs at both ends of a PW are not in the same autonomous system (AS), multi-segment PWs need to be used. In this case, you need to configure switching PWs on the SPEs.
In an L2VPN environment, multiple VPNs may share a tunnel. As a result, VPNs preempt bandwidth. VPN traffic cannot be forwarded or discarded based on service priorities, and non-VPN traffic also preempts VPN bandwidth. The VPN services carried over a tunnel have different resource requirements. The mpls switch-l2vc command sets QoS parameters for the switching PW to meet VPWS resource requirements without affecting the QoS of other VPNs.Prerequisites
MPLS and L2VPN have been enabled.
Configuration Impact
For a dynamic switching PW, the SPE does not negotiate the PW signaling but transparently transmits the PW information of the PEs at both ends.
Running the undo mpls switch-l2vc all command deletes all switching PWs on a device. Therefore, exercise caution when running this command. After the mpls switch-l2vc command is run, PWs carry service packets based on the configured bandwidth.Follow-up Procedure
Run the display mpls switch-l2vc command to check whether the VC status is up.
Precautions
The combination of the Peer IP, PW ID and PW type must be unique on a node. The PW IDs at the two ends of an MS-PW can be the same.
The VCCV feature is enabled by default and does not need to be configured. If the control word function is enabled, VCCV in control word mode is supported by default.<HUAWEI> system-view [~HUAWEI] mpls [*HUAWEI-mpls] quit [*HUAWEI] mpls l2vpn [*HUAWEI-l2vpn] quit [*HUAWEI] mpls switch-l2vc 1.1.1.9 100 between 3.3.3.9 100 encapsulation vlan
