Virtual Private LAN Services (VPLS) • VPLS defines an architecture that delivers Ethernet Multipoint Services (EMS) over an MPLS network • VPLS operation emulates an IEEE Ethernet bridge • Two VPLS drafts in existance Draft-ietf-l2vpn-vpls-ldp-01 Cisco’s Implementation draft-ietf-l2vpn-vpls-bgp-01 CE PE MPLS Network PE VPLS Is An Architecture CE CE

  12. 12. 121212© 2004 Cisco Systems, Inc. All rights reserved. VPN & VPLS Desirable Characteristics • Auto-discovery of VPN membership Reduces VPN configuration and errors associated with configuration • Signaling of connections between PE devices associated with a VPN • Forwarding of frames AToM uses Interface based forwarding VPLS uses IEEE 802.1q Ethernet Bridging techniques • Loop prevention MPLS Core will use a full mesh of PWs and “split-horizon” forwarding H-VPLS edge domain may use IEEE 802.1s Spanning Tree, RPR, or SONET Protection

  15. 15. 151515© 2004 Cisco Systems, Inc. All rights reserved. VPLS: Layer 2 Forwarding Instance Requirements Flooding / Forwarding: • MAC table instances per customer and per customer VLAN (L2- VRF idea) for each PE • VSI will participate in learning, forwarding process • Uses Ethernet VC-Type defined in pwe3-control-protocol-xx Address Learning / Aging: • Self Learn Source MAC to port associations • Refresh MAC timers with incoming frames • New additional MAC TLV to LDP Loop Prevention: • Create partial or full-mesh of EoMPLS VCs per VPLS • Use “split horizon” concepts to prevent loops • Announce EoMPLS VPLS VC tunnels A Virtual Switch MUST operate like a conventional L2 switch!
  16. 16. 161616© 2004 Cisco Systems, Inc. All rights reserved. VPLS Overview: Flooding & Forwarding • Flooding (Broadcast, Multicast, Unknown Unicast) • Dynamic learning of MAC addresses on PHY and VCs • Forwarding -Physical port -Virtual circuit ??? Data SA ?

  18. 18. 181818© 2004 Cisco Systems, Inc. All rights reserved. VPLS Overview: MAC Address Withdrawal X LDP Address Withdrawal • Primary link failure triggers notification message • PE removes any locally learned MAC addresses and sends LDP address withdrawal (RFC3036) to remote PEs in VPLS • New MAC TLV is used

VPLS Overview: VPLS Loop Prevention MPLS Network - LDP between VPLS members - EoMPLS PW to each peer CEs PEs PE view • Each PE has a P2MP view of all other PEs it sees it self as a root bridge, split horizon loop protection • Full mesh topology obviates STP requirements in the service provider network • Customer STP is transparent to the SP / customer BPDUs are forwarded transparently • Traffic received from the network will not be forwarded back to the network

VPLS Overview: VPLS Learning • Unqualified Single port assigned for all customer VLANs Single broadcast domain for all customer VLANs Single MAC address space (no overlap!) • Qualified Each VLAN has its own VPLS instance A VLAN has its own broadcast space and MAC address space Customer MAC addresses MAY overlap One FIB per customer VLAN Broadcast domain limited to VLAN scope

VPLS Architecture: Characteristics – H-VPLS Benefits: • Best for larger scale deployment • Reduction in packet replication and signaling overhead on PEs • Full mesh for core tier (Hub) only • Attachment VCs “virtual switch ports” effected through Layer 2 tunneling mechanisms (AToM, L2TPv3, QinQ) • Expansion affects new nodes only (no re-configuring existing PEs) Drawbacks: • More complicated provisioning • MPLS Edge H-VPLS requires MPLS to u-PE Complex operational support Complex network design Expensive Hardware support
