In this chapter from Building Data Centers with VXLAN BGP EVPN: A Cisco NX-OS Perspective , the author team discusses two different options for handling BUM or multidestination traffic— leveraging multicast replication in the underlying network and using a multicast-less approach called ingress replication. Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on short path labels rather than long network addresses, thus avoiding complex lookups in a routing table and speeding traffic flows. With the use of BGP as the control plane protocol, EVPN now enabled edge devices to utilize multiple active links and per flow load-balancing between the CE and PEs. Cisco IOS XE Fuji 16.

Please refer to the following cheatsheet if you are not familiar with EVPN Terminology. BGP EVPN L2 VNI VXLAN. Traditionally, the data center is built as a flat Layer 2 network with issues such as flooding, limitations in redundancy and provisioning, and high volumes of MAC addresses learned, which cause churn at node failures. With this being said, people often refer to Layer 3 MPLS VPN service as simple 'MPLS'. A vulnerability in the Multiprotocol Label Switching (MPLS) Operations, Administration, and Maintenance (OAM) implementation of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, adjacent attacker to trigger a denial of service (DoS) condition on an affected device. Cisco has a protocol called Easy Virtual Networking. MPLS and Network Virtualization Overlay (NVO), an example of which is Virtual Extensible LAN (VXLAN), are defined as data plane options.

RFC 7432 BGP MPLS-Based Ethernet VPN February 2015 The policy attributes of EVPN are very similar to those of IP-VPN. Layer 2 (VPLS) 3. When EVPN introduced all-active multi-homing, it offered a new redundancy option not available with VPLS. The manipulation with an unknown input leads to a denial of service vulnerability (Crash). BGP EVPN L3 VNI (NX-OS 9) This document [Cisco Nexus 9000 Series NX-OS Release Notes, …. x Cisco Programmable Fabric with VXLAN BGP EVPN Release Notes Minimum and Suggested Cisco NX-OS Releases for Cisco Nexus 7000 Series Switches. Madrid, Spain. While this book focuses on Cisco's Nexus 9000 product offering of the aforementioned technologies, it still makes for an excellent reference manual for both VxLAN and EVPN. During my time working for MegaFon I achieved the CCNP level of certification in R&S (Routing and ~Switching) as well as SP (Service Provider). Showing the different applications of Integrated Routing and Bridging for IRB. Leading networking vendors (like Cisco, Juniper, and Alcatel) are promoting another PBB-EVPN and EVPN technology to address challenges in data center area. David Jansen and Lukas Krattiger, authors of Cisco Programmable Fabric Using VXLAN with BGP EVPN LiveLessons , explain how Cisco's BGP EVPN enhances VXLAN encapsulation with Layer 2 and Layer 3 benefits. MPLS encapsulation used with EVPN control plane requires end-to-end LSPs between PE devices. EVPN Multihoming requires that all switches in a given network must be EVPN Multihoming capable. Shekhar Juniper J. Products (1) Cisco Nexus 7000 Series Switches ; When RD is configured under the VRF using either "rd auto" or "rd ASN" and vrf isn't being used in mpls / evpn setup. EVPN Multi-Homed All-Active ethernet access provides redundancy and optimal forwarding and load-balancing. [Network Computing]Recent changes in LSR protocols. In the physical network, a Juniper Networks device that functions as a Layer 2 or Layer 3 VXLAN gateway can enacapsulate and de-encapsulate data packets. #R-1 [email protected]> show bgp group Group Type: Internal AS: 65000 Local AS: 65000 Name: MPLS Index: 0 Flags: Holdtime: 0 Total peers: 1 Established: 1 10. It doesn’t have to rely on data plane learning, so can cut down on flooding between sites. PDF - Complete Book (6. The end result could be a local mac indicating it has an MPLS remote. Leaf-1# sh bgp l2vpn evpn sum BGP summary information for VRF default, address family L2VPN EVPN BGP router identifier 10. The EVPN/PBB-EVPN specifications introduce. Will EVPN replace MPLS? MPLS is a data-plane protocol, while EVPN is a control-plane protocol. 4 External links.
