Configuring MAC Learning Protection
To configure MAC learning protection, configure split horizon, MAC protection, and SAP
parameters.
Example: config>service# vpls 800
config>service>vpls# split-horizon-group "DSL-group1"
config>service>vpls>split-horizon-group# restrict-protected-src
config>service>vpls>split-horizon-group# restrict-unprotected-dst
config>service>vpls>split-horizon-group# exit
config>service>vpls# mac-protect
config>service>vpls>mac-protect# mac FF:FF:FF:FF:FF:FF
config>service>vpls>mac-protect# exit
config>service>vpls# sap 1/1/3:100
config>service>vpls>sap# restrict-protected-src
The following example displays the VPLS configuration with split horizon enabled:
