Step 2 Run:
vsi vsi-name auto
VSIs are created and the automatic member discovery mechanism is adopted.
The Kompella VPLS does not directly operate on the connection between CEs. Each CE has a
globally unique number. On a PE, a VSI is created for each CE that is directly connected to this
PE device.
Step 3 Run:
pwsignal bgp
BGP is configured as the PW signaling protocol and the VSI BGP view is displayed.
Step 4 Run:
route-distinguisher route-distinguisher
The RD is configured for the VSI.
After configuring BGP as the PW signaling protocol, you must configure the RD of the VSI to
validate the VSI.
Step 5 Run:
vpn-target vpn-target & <1-16> [ both | export-extcommunity | import-extcommunity ]
The VPN Target is configured for the VSI.
When configuring the VPN Target of the VSI, ensure that the VPN target of export-
extcommunity is the same as that of import-extcommunity.
Step 6 Run:
site site-id [ range site-range ] [ default-offset { 0 | 1 } ]
Information about the sites of the VSI is configured.
The site ID of the local end must be less than the sum of the site-range value and default-
offset value on the peer end. The site ID of the local end must be greater than the default-
offset value of the peer end.
Step 7 Run:
quit
The VSI view is displayed.
Step 8 Run:

The system view is displayed.
Step 9 (Optional) Run:
vpls bgp encapsulation { ethernet | vlan }
The encapsulation type is configured for the VPLS.

NOTE
At present, the VSIs of the two dual-homed PEs can be configured with only one label block. To enlarge
the range, use the undo site command to delete all the original sites and then configure a larger range. In
addition, the VSIs of the two dual-homed PEs can be configured with only one AC.
