• Not to be confused with Network Function Virtualization (NFV)

• Available in 2 flavors: nV Edge and nV Satellite

• nV Edge: • Clustering technology – two ASR-9K's clustered as 1 • Works on Edge ASR-9K's • Provides redundancy and availability

• nV Satellitle • Geared towards a distributed edge • Standalone devices act as remote ASR-9K linecards • ASR-9K acts as the “brain” for remotely distributed “line card”

BRKSPG-2202 © 2017 Cisco and/or its affiliates. All rights reserved. Cisco Public 37 What is EVPN? EVPN RFC • EVPN family introduces next generation 7432 solutions for Ethernet services • BGP control-plane for Ethernet Segment and MAC distribution and learning over P2P Multipoint MPLS core • Same principles and operational experience of IP VPNs • No use of Pseudowires EVPN-VPWS • Uses MP2P tunnels for unicast RFC RFC • Multi-destination frame delivery via ingress draft-ietf-bess-evpn- 7432 7623 replication (via MP2P tunnels) or LSM vpws • Multi-vendor solutions

• Cisco leader in industry standardization EVPN PBB-EVPN efforts

• Packets originated from MAC2 arrives Flip/flopping ! MAC2 at both PE3 and PE4 which get MAC1 CE1 PE1 PE3 CE2 forwarded subsequently to PE1. PE1 keeps flip/flopping between PE3 and PE4 for learning of MAC2!!

PE2 PE4

MAC1 MAC2 • BUM packets forwarded from PE1 CE1 PE1 PE3 CE2 can get loopback to the originating CE Echo !

PE2 PE4

• VPLS cannot do proper load-balancing MAC1 CE2 MAC2 because doesn’t support Aliasing. CE1 PE1 PE3 When PE3 wants to forward a packet with destination address MAC1, it Load balancing needs to send it to both PE1 and PE2 even though it only learned MAC1 from PE1. PE2 PE4

M1 M2 • Existing VPLS solutions do not offer CE1 PE1 PE3 CE2 an All-Active per-flow redundancy Echo ! PE2 PE4 • Looping of Traffic Flooded from PE

M1 DuplicateM2 ! • Duplicate Frames from Floods from PE1 PE3 CE2 the Core CE1

• MAC Flip-Flopping over Pseudowire PE2 PE4 • E.g. Port-Channel Load-Balancing M1 M2 does not produce a consistent hash- MAC value for a frame with the same CE1 PE1 Flip-Flop PE3 CE2 source MAC (e.g. non MAC based Hash-Schemes) PE2 PE4

Highlights Control-plane address Data-plane address advertisement / learning • Next generation solution for Ethernet learning from Access over Core multipoint (E-LAN) services

VID 100 • PEs run Multi-Protocol BGP to advertise SMAC: M1 & learn Customer MAC addresses (C- DMAC: F.F.F PE1 PE3 MACs) over Core • Same operational principles of L3VPN CE1 CE3

• Learning on PE Access Circuits via data- C- C- MAC:M1 MAC:M3 plane transparent learning PE2 PE4 • No pseudowire full-mesh required • Unicast: use MP2P tunnels • Multicast: use ingress replication over MP2P BGP MAC adv. Route tunnels or use LSM EVPN NLRI MAC M1 via PE1 • Standardized at IETF – RFC 7432

PBB Ethernet VPN PBB Highlights Backbone EVPN Edge Bridge

• Next generation solution for Ethernet multipoint (E-LAN) services by combining Provider Control-plane address Data-plane address advertisement / Backbone Bridging (PBB - IEEE 802.1ah) and learning from Core learning over Core (B- Ethernet VPN • Remote C-MAC to MAC) remote B-MAC binding • Data-plane learning of local C-MACs and remote C-MAC to B-MAC binding Data-plane address PE1 PE3 learning from Access • Local C-MAC to local • PEs run Multi-Protocol BGP to advertise local B-MAC: B-MAC binding B-M2 Backbone MAC addresses (B-MACs) & learn B-M1 remote B-MACs CE1 CE3 • Takes advantage of PBB encapsulation to simplify BGP control plane operation – faster convergence MPLS C-MAC: • C-MAC: Lowers BGP resource usage (CPU, memory) on M MB deployed infrastructure (PEs and RRs) A B-MAC: B-M2 B-M1
