To suppress unidirectional multicast and unknown unicast packets, enable CFM for PBB VPLS.
In PBB VPLS, SPEs broadcast unidirectional multicast and unknown unicast packets to all VSIs in a VPLS domain. To suppress unidirectional multicast and unknown unicast packets, enable CFM for PBB VPLS. After CFM is enabled, SPEs can learn the B-SMAC addresses of UPEs and unidirectionally forward unidirectional multicast and unknown unicast packets to UPEs. When network resources are tight, enabling CFM for PBB VPLS is recommended.
