VPLS Applicability Draft draft-lasserre-l2vpn-vpls-ldp-applic-00 Marc Lasserre - Riverstone Xipeng Xiao – Riverstone Yetik Serbest – SBC Cesar Garrido - Telefonica

VPLS Applicability Draft draft-ietf-l2vpn-vpls-ldp defines a method –for signaling MPLS connections between member PEs of a VPN –for forwarding Ethernet frames over such connections. draft-lasserre-l2vpn-vpls-ldp-applic describes the applicability of such procedures to provide VPLS services –Compares VPLS characteristics against L2VPN requirements draft

Content of Applicability Draft Overview of VPLS –Operation of control, data and management planes –Alternative approaches to VPLS Scalability Deployment Aspects

VPLS Scalability Mesh connectivity (full mesh, hub & spoke) Number of MAC addresses (switch or router interconnect, MAC limiting per VPLS) Broadcast limiting Replication (HVPLS, IGMP snooping)

VPLS Deployment Aspects Service provisioning & management –PE discovery –Traffic conditioning –TE –Monitoring & accounting Migration Impacts –From 802.1Q/QinQ to VPLS Multihoming (STP, primary/secondary) Loop prevention

VPLS Deployment Aspects (Cont’d) Packet reordering QoS (802.1P, ToS/DSCP to Exp/Tunnel mapping) Multi-domain connectivity (HVPLS spoke, interworking with BGP VPN) Interworking with FR/ATM/PPP attachment circuits –Dataplane interworking (Bridged Ethernet) –Service profile, OAM, circuit management mapping to be specified Security –Traffic isolation (per VPLS FIB) –DoS

VPLS Applicability: Next Steps Describe missing requirements and add metrics as defined in draft-ietf-l2vpn- requirements (e.g. unauthorized CE access, capacity sizing) Solicit comments on list Become a WG document
