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 […]
Printing files content in output cat command The “cat” command stands for concatenate. It is one of the most useful commands in Linux. This command displays file content in the output concatenates and creates files. Syntax cat [OPTION] [FILE]………… Example Cat without any options displays the file’s content in the output. If sending multiple files […]
What is the SSL Offloading solution, and how does it work? SSL protocol (of course, this protocol is obsolete, and its replacement version is TLS, but the name of the SSL Offloading solution has not changed, for that reason, we use the title SSL) is a protocol that is used to encrypt and decrypt data […]
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. […]
SSH or Secure Shell is a secure protocol for remote communication between systems and servers. This protocol is an alternative to Telnet, which has security and encryption mechanisms. This article will discuss 7 tips to secure the SSH protocol. In the past, the Telnet protocol was used to establish remote communication, execute commands, and manage […]
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 […]
