Distributed VPLS SAPs
To configure a distributed VPLS service, you must configure service entities on originating and 
far-end nodes. You must use the same service ID on all ends (for example, create a VPLS service 
ID 9000 on ALA-1, ALA-2, and ALA-3). A distributed VPLS consists of a SAP on each 
participating node and an SDP bound to each participating node.
For SDP configuration information, see Configuring an SDP on page 68. For SDP binding 
information, see Configuring SDP Bindings on page 400.
This example configures a distributed service between ALA-1, ALA-2, and ALA-3.
Example: *A:ALA-1>config>service# vpls 9000 customer 6 create
*A:ALA-1>config>service>vpls# sap 1/2/5:0 create
*A:ALA-1>config>service>vpls>sap$ no shutdown
*A:ALA-1>config>service>vpls>sap# multi-service-site west
*A:ALA-1>config>service>vpls>sap# exit
*A:ALA-1>config>service>vpls#
*A:ALA-2>config>service# vpls 9000 customer 6 create
*A:ALA-2>config>service>vpls# sap 1/1/2:22 create
*A:ALA-2>config>service>vpls>sap$ no shutdown
*A:ALA-2>config>service>vpls>sap# multi-service-site west
*A:ALA-2>config>service>vpls>sap# exit
*A:ALA-2>config>service>vpls#
*A:ALA-3>config>service# vpls 9000 customer 6 create
*A:ALA-3>config>service>vpls# sap 1/1/3:33 create
*A:ALA-3>config>service>vpls>sap$ no shutdown
*A:ALA-3>config>service>vpls>sap# multi-service-site west
*A:ALA-3>config>service>vpls>sap# exit
*A:ALA-3>config>service>vpls#
The following example displays a sample configuration of the VPLS SAPs in preparation of a 
VPLS service between ALA-1, ALA-2, and ALA-3.
