Configuring a VPLS Service with CLI
Configuring VPLS SAPs with Split Horizon
Note: Split Horizon group is supported only on 7210 SAS-M devices configured in Network
mode.
To configure a VPLS service with a split horizon group, add the split-horizon-group parameter
when creating the SAP. Traffic arriving on a SAP within a split horizon group will not be copied
to other SAPs in the same split horizon group.
The following example displays a VPLS configuration with split horizon enabled:
*A:ALA-1>config>service# info

vpls 800 customer 6001 vpn 700 create
exit
...
