Binding a VSI to an AC Interface

Based on the type of link between a PE and a CE, a VSI and an AC interface are bound in various views.

Context

Based on the type of link between a PE and a CE, a VSI is bound to an AC interface on the PE in one of the following modes:

Binding the VSI to the GE interface when the PE and the CE are connected through the Ethernet interface
Binding the VSI to the GE sub-interface when the PE and the CE are connected through the Ethernet sub-interface or GE sub-interface
Binding the VSI to the VLANIF interface when the PE and the CE are connected through the VLANIF interface
Binding the VSI to the VE interface when the PE and the CE are connected through the VE interface
Binding the VSI to the Eth-Trunk when the PE and the CE are connected through the Eth-Trunk interface
Binding the VSI to the Eth-Trunk sub-interface when the PE and the CE are connected through the Eth-Trunk sub-interface
Binding the VSI to a sub-interface for QinQ VLAN tag termination. For details, refer to the Configuration Guide - LAN Access & MAN Access.

In the VPLS application, different CEs are transparently connected in the same LAN segment through VSIs, and the IP addresses of the CEs must be different. The IP address of the interface that connects the PE to the CE and the IP address of the CE must be in different network segments. Otherwise, the local CE may learn incorrect ARP entries. This leads to traffic loss between CEs in the same VSI.

Procedure

Bind a VSI to an Ethernet interface.
Perform the following steps on the endpoint PEs of a PW.
1. Run system-view
  The system view is displayed.
2. Run interface interface-type interface-number
  The Ethernet interface view is displayed.
3. Run l2 binding vsi vsi-name
  The VSI is bound to the Ethernet interface.
Bind a VSI to an Ethernet sub-interface.
Perform the following steps on the endpoint PEs of a PW.
1. Run system-view
  The system view is displayed.
2. Run interface interface-type interface-number
  The Ethernet sub-interface view is displayed.
3. Run vlan-type dot1q vlan-id
  The VLAN type of the interface is configured.
4. Run l2 binding vsi vsi-name
  The VSI is bound with the Ethernet sub-interface.
Bind a VSI to a VLANIF interface.
Perform the following steps on the endpoint PEs of a PW.
1. Run system-view
  The system view is displayed.
2. Run interface vlanif vlan-id
  The VLANIF interface view is displayed.
3. Run l2 binding vsi vsi-name
  The VLANIF interface is bound to the VSI.
Bind a VSI to an L2VE sub-interface.
Perform the following steps on the endpoint PEs of a PW.
1. Run system-view
  The system view is displayed.
2. Run interface virtual-ethernet interface-number interface-number
  The L2VE sub-interface view is displayed.
3. Run vlan-type dot1q vlan-id
  The VLAN ID of the L2VE sub-interface is configured.
4. Run l2 binding vsi vsi-name
  The L2VE interface is bound to a VSI.
Bind a VSI to an Eth-Trunk interface.
Perform the following steps on the endpoint PEs of a PW.
1. Run system-view
  The system view is displayed.
2. Run interface eth-trunk trunk-id
  An Eth-Trunk interface is created.
3. Run quit
  Return to the system view.
4. Run interface interface-type interface-number
  The view of the interface to be added into the Eth-Trunk is displayed.
5. Run eth-trunk trunk-id
  The interface is added into the Eth-Trunk.
  
  Before adding an interface into an Eth-Trunk, ensure the interface is not configured with any Layer 3 attributes such as IP address and any services.
  
  The types of the interfaces on both ends of an Eth-Trunk member link must be the same.
6. Run quit
  Return to the system view.
7. Run interface eth-trunk trunk-id
  The Eth-Trunk interface view is displayed.
8. Run l2 binding vsi vsi-name
  The Eth-Trunk interface is bound with the VSI.
Bind a VSI to an Eth-Trunk sub-interface.
Perform the following steps on the endpoint PEs of a PW.
1. Run system-view
  The system view is displayed.
2. Run interface eth-trunk trunk-id
  An Eth-Trunk interface is created.
3. Run quit
  The system view is displayed.
4. Run interface interface-type interface-number
  The view of the interface to be added into the Eth-Trunk is displayed.
  
  An Eth-Trunk member interface cannot be configured with a static MAC address.
  
  Member interfaces of a trunk cannot be Eth-Trunk interfaces .
5. Run eth-trunk trunk-id
  The interface is added into the Eth-Trunk.
  
  Before adding an interface into an Eth-Trunk, ensure the interface is not configured with any Layer 3 attributes such as IP address and any services.
  
  The types of the interfaces on both ends of an Eth-Trunk member link must be the same.
6. Run quit
  Return to the system view.
7. Run interface eth-trunk trunk-id .subnumber
  The Eth-Trunk sub-interface view is displayed.
8. Run vlan-type dot1q vlan-id
  The VLAN encapsulation type is configured on the sub-interface.
9. Run l2 binding vsi vsi-name
  The Eth-Trunk sub-interface is bound with the VSI.
