Binding an AC Interface to a VSI

AC interfaces can be bound to VSIs based on access link types.

Context

The binding scenarios are classified as follows based on access link types:

Binding an Ethernet interface to a VSI: A PE uses GE interface to connect to a CE.
Binding an Ethernet sub-interface to a VSI: A PE uses GE sub-interface to connect to a CE.
Binding a VLANIF sub-interface to a VSI: A PE uses a VLANIF interface to connect to a CE
Binding an L2VE sub-interface to a VSI: A PE uses an L2VE sub-interface to connect to a CE.
Binding an Eth-Trunk interface to a VSI: A PE uses an Eth-Trunk interface to connect to a CE.
Binding an Eth-Trunk sub-interface to a VSI: A PE uses an Eth-Trunk sub-interface to connect to a CE.
Binding a dot1q VLAN tag termination sub-interface to a VSI: A PE uses a dot1q VLAN tag termination sub-interface to connect to a CE.

On a VPLS network, CEs transparently connect to each other on the same LAN segment and therefore must have different IP addresses. In addition, PE interfaces that connect to CEs must have different network segment addresses as connected CEs. Otherwise, local CEs may learn incorrect ARP entries, causing traffic loss.

Procedure

Bind an Ethernet interface to a VSI.
Perform the following steps on the PEs at both ends 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 Ethernet interface is bound to a VSI.
4. Run commit
  The configuration is committed.
Bind an Ethernet sub-interface to a VSI.
Perform the following steps on the PEs at both ends of a PW.
1. Run system-view
  The system view is displayed.
2. Run interface interface-type interface-number interface-number
  The Ethernet sub-interface view is displayed.
3. Run vlan-type dot1q vlan-id
  A VLAN encapsulation type is configured.
4. Run l2 binding vsi vsi-name
  The Ethernet sub-interface is bound to a VSI.
5. Run commit
  The configuration is committed.
Bind a VLANIF interface to a VSI.
Perform the following steps on the PEs at both ends 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 a VSI.
4. Run commit
  The configuration is committed.
Bind an L2VE sub-interface to a VSI.
Perform the following steps on the PEs at both ends of a PW.
1. Run system-view
  The system view is displayed.
2. Run interface virtual-ethernet interface-type interface-number
  The VE sub-interface view is displayed.
3. Run vlan-type dot1q vlan-id
  A VLAN ID is configured.
4. Run l2 binding vsi vsi-name
  The L2VE sub-interface is bound to a VSI.
5. Run commit
  The configuration is committed.
Bind an Eth-Trunk interface to a VSI.
Perform the following steps on the PEs at both ends 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 interface view is displayed.
5. Run eth-trunk trunk-id
  The interface is added to the Eth-Trunk interface.
  
  An interface to be added to an Eth-Trunk interface cannot have services or Layer 3 configurations.
  
  One Ethernet interface can be added only to one Eth-Trunk interface. Before adding an Ethernet interface to an Eth-Trunk interface, ensure that the Ethernet interface does not belong to any Eth-Trunk interface.
  
  The interfaces at the two ends of an Eth-Trunk member link must be of the same type.
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 to a VSI.
9. Run commit
  The configuration is committed.
Bind an Eth-Trunk sub-interface to a VSI.
Perform the following steps on the PEs at both ends 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 interface view is displayed.
  
  Note that Eth-Trunk member interfaces cannot have statically configured MAC addresses.
5. Run eth-trunk trunk-id
  The interface is added to the Eth-Trunk interface.
  
  An interface to be added to an Eth-Trunk interface cannot have services or Layer 3 configurations.
  
  One Ethernet interface can be added only to one Eth-Trunk interface. Before adding an Ethernet interface to an Eth-Trunk interface, ensure that the Ethernet interface does not belong to any Eth-Trunk interface.
  
  The interfaces at the two ends of an Eth-Trunk member link must be of the same type.
6. Run quit
  Return to the system view.
7. Run interface eth-trunk trunk-id interface-number
  The Eth-Trunk sub-interface view is displayed.
8. Run vlan-type dot1q vlan-id
  A VLAN encapsulation type is configured.
9. Run l2 binding vsi vsi-name
  The Eth-Trunk sub-interface is bound to a VSI.
10. Run commit
  The configuration is committed.
