The overlay refers to the virtual Ethernet segment created by this forwarding. This Jun 21, 2021 · The integrated routing and bridging (IRB) in VXLAN/EVPN fabrics allows to suppress the ARP request flooding of transparent bridging, so this is often done. So all information in this post applicable only to MX devices. The reachability of the VTEPs is achieved by using either IPv6 Link-Local or IPv6 global addressing along with an IPv6 capable routing protocol like IS-IS, OSPFv3 or BGP. Chan . This is due to the entire fabricpath domain looking like one physical bridge. This includes the ability to L2 bridge other Ethernet networks (wired LAN, WiFi, virtual backplanes, etc. Similar to the transparent bridge the forwarding table entries are removed after aging timer expires. Networking is a central part of Kubernetes, but it can be challenging to understand exactly how it is expected to work. One suspects the 1000v may do it in the future. It should be noted that encapsulation introduces an overhead that reduces the effective network throughput.
