8 Cisco EVC Fundamentals

9 Cisco EVC Building Blocks Cisco EVC Uses the Following New Concepts: Ethernet Flow Point (EFP) Transport-agnostic abstraction of an Ethernet service on an interface Ethernet Virtual Circuit (EVC) Device local object (container) for network-wide service parameters Bridge Domain (BD) Ethernet Broadcast Domain local to a device Bridge Domain Interface (BDI) Logical Layer 3 interface associated with a BD to perform integrated routing and bridging 9

10 Cisco EVC Building Blocks Ethernet Flow Point (EFP) CE A3 EVC Blue CE A2 CE A1 CE B2 CE B1 EFP EVC Red EFP Interface EFP EFP Instance of a MEF EVC on a port Also defined as Service Instance Classify frames belonging to a particular Ethernet Service Apply features selectively to service frames Define forwarding actions and behavior 10

11 Cisco EVC Building Blocks Ethernet Virtual Circuit EFP EVC EVC Management Plane EFP Interface EFP EFP Representation of a MEF EVC on the device Management Plane container Hosts global EVC attributes One-to-many mapping from EVC to EFPs 11

12 Cisco EVC Building Blocks Bridge Domain EFP EVC EVC Management Plane EFP Interface EFP EFP Bridge Domain Broadcast Domain internal to the device Allows decoupling broadcast domain from VLAN Per port VLAN significance One-to-many mapping from BD to EFPs 12

13 Cisco EVC Building Blocks Bridge Domain vs. VLAN Bridge VLAN VLAN Bridge Domain EFP VLAN VLAN Bridge EVC Bridge VLAN bridge has 1:1 mapping between VLAN and internal Broadcast Domain VLAN has global per-device significance EVC bridge decouples VLAN from Broadcast Domain VLAN treated as encapsulation on a wire VLAN on a wire mapped to internal Bridge Domain via EFPs Net result: per-port VLAN significance 13

14 Cisco EVC Building Blocks Bridge Domain Interface L2 Network BD BDI L3 Network EFP Bridge Domain Interface L3 Routing L3 Interface Logical Layer 3 (routed) port associated with a Bridge Domain Support termination of Ethernet traffic to IP / L3VPN (VRF aware) Only a single BDI per Bridge Domain is allowed Maintains Admin State (CLI) and Operational State (derived from BD) If all EFPs in BD are Down or Admin-Down, then BDI operational state will be Down 14

17 Operation and Packet Flow Flexible Service Mapping

18 Flexible Service Mapping Single Tagged VLAN Matching Untagged traffic Single VLAN ID value Single VLAN ID Range (contiguous) Single VLAN ID List Single VLAN ID Range and List Untagged 30 PORT GE / 10GE Range List Range and List Ethernet Flow Points S-VLAN C-VLAN 18

19 Flexible Service Mapping Double Tagged VLAN Matching PORT GE / 10GE Outer VLAN, Inner VLAN Outer VLAN and Range of Inner VLANs (contiguous) Outer VLAN and List of Inner VLANs Outer Inner Outer Inner Range Outer Inner List Outer VLAN and Range and List of Inner VLANs S-VLAN C-VLAN 19

20 Flexible Service Mapping Header Matching PORT GE / 10GE Single VLAN, single 802.1p (COS) value Single VLAN, COS List/Range Outer VLAN, outer COS and Inner VLAN Outer VLAN, Inner VLAN and inner COS Single VLAN, Ethertype value (PPPoE, IPv4, IPv6) Outer VLAN, Inner VLAN and Ethertype value (PPPoE, IPv4, IPv6) COS COS Range PPPoE COS 5 COS 2-5 PPPoE S-VLAN C-VLAN 20

21 Flexible Service Mapping Comprehensive Matching Capabilities PORT GE / 10GE EFP construct classifies L2 flows on Ethernet interfaces Single Tagged Double Tagged Untagged Header/Payload Ethernet Flow Pointss 400 COS COS PPPoE S-VLAN C-VLAN 21

22 Flexible Service Mapping Loose Match Classification Rule Cisco EVC follows a Loose Match classification model Unspecified fields are treated as wildcard encap dot1q 10 matches any frame with outer tag equal to encap dot1q 10 second-dot1q 50 matches any frame with outer-most tag as 10 and second tag as

23 Flexible Service Mapping Longest Match Classification Rule Cisco EVC follows a Longest Match classification model Frames are mapped to EFP with longest matching set of classification fields 10 EFP VLAN S-VLAN 10 C-VLAN 100 S-VLAN 10 C-VLAN Interface 23

24 Flexible Service Mapping EFP with Default Encapsulation Matches all frames unmatched by any other EFP on a port VLAN 10 VLAN 20 VLAN 10 VLAN 20 VLAN 50 Untagged Interface EFP Default If default EFP is the only one configured on a port, it matches all traffic on the port (tagged and untagged) VLAN 10 VLAN 20 VLAN 50 Untagged Interface EFP Default 24

25 Flexible Service Mapping Trunk EFP Matches a range and/or list of VLANs. Allocates each VLAN to a unique bridge-domain. Emulates switchport mode trunk behavior. VLAN 10 BD VLAN 20 VLAN 50 Interface Trunk EFP BD BD 25

26 Operation and Packet Flow Advanced Frame Manipulation

27 Advanced Frame Manipulation PUSH Operations Add one VLAN tag Add two VLAN tags

28 Advanced Frame Manipulation POP Operations Remove one VLAN tag Remove two VLAN tags

29 Advanced Frame Manipulation Translation Operations 1:1 VLAN Translation :2 VLAN Translation :1 VLAN Translation :2 VLAN Translation

30 Advanced Frame Manipulation VLAN Tag Manipulation PUSH operations POP operations TRANSLATION operations

31 Encapsulation Adjustment Considerations EoMPLS PW VC Type and EVC VLAN Rewrites VLAN tags can be added, removed or translated prior to VC label imposition or after disposition Any VLAN tag(s), if retained, will appear as payload to the VC VC label imposition and service delimiting tag are independent from EVC VLAN tag operations Dummy VLAN tag RFC 4448 (sec 4.4.1) VC service-delimiting VLAN-ID is removed before passing packet to Attachment Circuit processing MPLS Imposition EVC VLAN Rewrite AC MPLS Disposition MPLS Label Disposition POP 1 VLAN tag 4 PW VC Type 4 VC Type 5 PUSH 1 VLAN tag 5 Dummy VLAN tag Dummy VLAN tag PW MPLS Label Imposition EVC VLAN Rewrite AC 31

32 Operation and Packet Flow Multiplexed Forwarding Services

33 Multiplexed Forwarding Services Cisco EVC supports flexible access VLAN to forwarding service mapping 1-to-1 access VLAN to a service Same port, multiple access VLANs to a service Multiple ports, multiple access VLANs to a service Forwarding services include: L2 point-to-point local connect L2 point-to-point xconnect L2 multipoint bridging L2 multipoint VPLS L2 point-to-multipoint bridging L3 termination 33

34 Multiplexed Forwarding Services Local and Bridged P2P and MP Forwarding Services Layer 2 P2P local services No MAC learning Two EFPs on same interface (hair-pin) Two EFPs on different interfaces Layer 2 MP bridged services MAC based forwarding and learning Local VLAN significance Bridge Domain (BD) different access VLANs in the same broadcast domain Split-horizon prevent communication between EFPs EFPs Split Horizon BD = Bridge Domain PW = Pseudowire Local Hair-Pin Layer 2 Point-to-Point BD Layer 2 Multipoint bridged VFI = Virtual Fwd Instance SVI = Switch Virtual Instance 34

35 Multiplexed Forwarding Services Provider Backbone Bridging (PBB) Forwarding Services PBB Forwarding Services MAC Tunneling per IEEE Std ah C-MAC BD performs MAC learning and forwarding based on Customer MAC Addresses (1:1 mapping between C- MAC BD & I-SID) B-MAC BD performs MAC learning and forwarding based on Backbone MAC Addresses MAC Tunnel performs PBB encapsulation/de-capsulation (I-SID, B- VLAN, Backbone Addresses Header) C-MAC BD C-MAC BD MAC Tunnel B-MAC BD EFPs C-MAC BD = Customer MAC Bridge Domain B-MAC BD = Backbone MAC Bridge Domain 35

37 Multiplexed Forwarding Services Rooted-Multipoint Forwarding Services (E-TREE) BD with Split Horizon Group can be used to implement rooted-multipoint forwarding service: Place all Leaf EFPs in Split Horizon Group Keep Root EFP outside the Split Horizon Group Net effect: Bidirectional connectivity between Root and all Leaf EFPs Leaf EFPs cannot communicate to each other Root EFP Leaf EFP Interface Bridge Domain BD Split Horizon Group Leaf EFP Leaf EFP 37
