The remarking of packets to and from an IP interface in an R-VPLS service corresponds to that supported on IP interface, even though the packets ingress or egress a SAP in the VPLS service bound to the IP service. Specifically, this results in the ability to remark the DSCP/prec for these packets.
Packets ingressing and egressing SAPs in the VPLS service (not routed through the IP interface) support the regular VPLS QoS and, therefore, the DSCP/prec cannot be remarked.
