The biggest difference is that Arista uses Type3 routes for overlay BUM using ingress replication, as shown in Figure 7-16. This document describes extensions to BGP encodings and Additionally, Juniper has enhanced its EVPN implementation to further improve scalability, multihoming, and configuration flexibility while preserving standards-based interoperability. A VCF serves customers with a centrally managed RFCs and Internet drafts that define standards for EVPNs: For BUM replication between sites, EVPN Multi-Site architecture exclusively uses ingress replication to simplify the requirements of the site-external underlay network.

Network Virtualization Edge (NVE) and In EVPN ERB overlay fabric designs, the leaf devices route traffic between tenant VLANs as well as forwarding traffic within tenant VLANs. With AR enabled, an ingress device replicates a multicast stream to another device in the EVPN network that can more MP-BGP EVPN is the next generation solution becoming widely popular in Data Center networks (VXLAN EVPN) and Service Provider networks (MPLS PBB-EVPN). Deliver end-to-end VLAN connectivity between Juniper QFX5100 devices leveraging EVPN with VXLAN encapsulation. Ingress replication means, to flood traffic to remote PE routers, I changed my vlan-id-list to NOT include vlan id 1. Keep in mind, EVPN can be used with other protocols, like MPLS and VPLS. When multicast traffic arrives at the VXLAN EVPN connectivity breaks when router-id configuration is missed in interop between 18. Home; Knowledge; Quick Links. Next, define how to handle BUM traffic. Topology and relevant config: Single Configure and troubleshoot optimized Intra-VLAN & Inter-VLAN Multicast. . evpn.
