Binding a Multi-homing Site to an AC Interface

Configure an AC interface and bind a multi-homing site to the AC interface to implement VPLS multi-homing.

Context

After a multi-homing site is configured, bind it to an AC interface so that it can establish a PW with the PE housing the AC interface for carrying end-to-end services.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The AC interface view is displayed.
(Optional) Run either of the following commands to configure Ethernet OAM:
- To associate CFM with an AC interface's blocked state, run the mpls l2vpn multi-homing trigger cfm md md-name ma ma-name command.
  CFM applies only to sub-interfaces. Run this command when CFM runs between a CE and a PE.
- To associate EFM with an AC interface's blocked state, run the mpls l2vpn multi-homing trigger efm command.
  EFM applies only to main interfaces. Run this command when EFM runs between a CE and a PE.
Run either of the following commands to configure binding:
- In VPLS multi-homing scenarios where a CE is single-homed to a PE, run:
  
  l2 binding vsi vsi-name
  
  The AC interface is bound to a VSI.
- In VPLS multi-homing scenarios where a CE is multi-homed to PEs, run:
  
  l2 binding vsi vsi-name multi-homing-site site-name
  
  The AC interface is bound to a multi-homing site
Run commit
The configuration is committed.
