Configuring a VPWS PW
This section describes how to establish a P2P VPWS PW between two PEs for communication.
Context
LDP VPWS is classified into two modes: PWE3-compatible and PWE3.
- PWE3-compatible mode: does not use Notification messages.
- PWE3 mode: uses Notification messages to advertise the PW status. By default, PWE3 VPWS is used.
Perform the following configurations on the endpoint PEs of a PW.
Procedure
- Run system-view
The system view is displayed.
- Run mpls l2vpn
MPLS L2VPN is enabled.
- (Optional) Run mpls l2vpn no-request-message peer ip-address
The function to send L2VPN Label Request messages to the remote peer is disabled.
- (Optional) Run mpls l2vpn ignore-te-oam-state
The PW is configured to ignore the recursive tunnel status monitored by MPLS OAM/MPLS-TP OAM.
- (Optional) Run mpls l2vpn auto-create-session
The function to automatically establish a remote LDP session is enabled.
- Run quit
Return to the system view.
- Run interface interface-type interface-number [ .subinterface-number ]
The AC interface view is displayed.
- (Optional) Run mpls l2vpn description description-text
An L2VPN description is configured for the AC interface.
- Run one of the following commands to create a VPWS PW according to the interface type:
Ethernet interface:
mpls l2vc { ip-address | pw-template template-name } * vc-id [ tunnel-policy policy-name [ endpoint endpoint-address color color-value ] | [ control-word | no-control-word ] | [ raw | tagged | ip-layer2 | ip-interworking ] | access-port | ignore-standby-state ] *
The VC IDs with the same encapsulation type must be unique on a PE.
The raw, tagged, and access-port parameters are available in this command only for Ethernet links. In addition, the access-port parameter can be configured only on Ethernet main interfaces.
If an Ethernet sub-interface is used, run the vlan-type dot1q vlan-id command in the interface view to configure the encapsulation type and VLAN ID of the Ethernet sub-interface.
The default tunnel policy uses LDP tunnels for VPWS PWs. To use a different type of tunnel, set the tunnel-policy policy-name parameter for the PW to reference the corresponding tunnel policy.
- (Optional) Run undo interface-parameter-type vccv
The VCCV byte is deleted from the Label Mapping message.
Run this command if LDP VPWS is configured for a device running VRP V800R005 or later and this device communicates with another device running VRP V300R001 or any branch version of VRP V300R001.
- (Optional) Run mpls l2vpn service-name service-name
An L2VPN service name is specified. The L2VPN service can then be maintained through an NMS based on the specified name.
- Run commit
The configuration is committed.
