Your endpoints still connect through classic ethernet to the leafs. In most practical implementations, we need redundancy between the endpoints and the leaf switches. So, we typically leverage vPC to provide us MC-LAG. vPC allows an endpoint connects to two leafs. The endpoint sees those switches as a single switch to which connected via a […]

Users connect to our data centers above the application layer. They are typically external to data centre resources. In this post, we will discuss how to connect our VXLAN-based data centre to an external Layer 3 network as well as the external connectivity to a Layer 2 network. Layer 3 could involve: the Internet, WAN, […]
From the previous posts, we learned that in order to differentiate between routes in the MP-BGP table, we include a 64-bit RD value along with the MAC address. In this post, we will discuss what else other than MAC address can propagate through BGP EVPN. Different route types carry BGP EVPN information. RFC 7432 defines […]
Integrated Route and Bridge (IRB) simply means first-hop routing. We have two different semantics for IRB: Asymmetric IRB: We have one L2VNI for each subnet we want to route between. Symmetric IRB: We have one L3VNI associated with the VRF which is used for all routed traffic Asymmetric IRB For now, forget the VXLAN and […]
In this section, we are going to discuss MP-BGP VXLAN with PIM to handle multi-destination traffic. So, your complete bipartite graph must support PIM. This is why in this post, we happened to choose loopback 254 on the spines for our PIM Anycast RP. VTEP V1 then sends out the packet toward the IP core. […]
we’ve come from the previous page here… ISO/OSI Model; Open Systems Interconnection ‘N’ Notation There are many terminologies that are used to describe the OSI Model and its layers, one such terminology is the N Notation. The letter N is often used to generically refer to ta number within the computer world. In the OSI […]
ISO/OSI Model; Open Systems Interconnection OSI stands for Open Systems Interconnection, it is a model which tells us how the application communicates over a network. Basically, seven marvelous layers that IT systems use to communicate and disseminate data over network, established in 1983 by the International Organization for Standardization (ISO) and became a working product […]
In this post, I am going to explain how the location-identity mapping database populates using MP-BGP. Consider the image below where VTEP01 takes the original ARP L2 frame from the HOST01. VTEP01 learns IP-MAC binding of the end host. BGP Update sends the information to the Route-Reflector (iBGP), which in turn forwards this update message to […]
In the last post, we talk about F&L with Ingress Replication (AKA head-end replication) to handle multi-destination traffic. In this section, we are going to discuss F&L with PIM to handle multi-destination traffic. So, your complete bipartite graph must support PIM. This is why in this post, we happened to choose loopback 254 on the […]
