Ether Channel Ether Channel is the Cisco term for bundling two or more physical Ethernet links for the purposes of aggregating available bandwidth. L2 Ethernet Channel combines the bandwidth of multiple layer 2 links, causing STP behavior to change. All in bundle are forwarding and treated as one link.L3 ether channel aggregates and optimizes the bandwidth of multiple layers three. Since there is only one neighbor relationship per switch interconnect, an ether channel bundles individual Ethernet links into a single logical link that provides the aggregated bandwidth of physical links….

Designing Layer 2 Campus Hello and welcome to the Designing Layer Two campus. This section is written in a guide format in that it covers a wide variety of topics in an extremely concise manner and explains how various architectures work, including relevant recommendations and their associated considerations. As a takeaway, you could create a design detailed enough to use as a working document for building a layer-two campus design. First of all, understand that the deployment is geared towards a small to large network with scalability, resiliency, security, low…

SD-WAN Dual-Router Hybrid Remote-Site Design This session is just the extension. That what we have a study, only one or two new points you’ll find now in case of dual router hybrid site design. So let me quickly show you the site diagram. So I have my branch and in this branch you can see that I have two devices in hybrid mode internet and MP TLS. But we are using tlock extension. So in between these two devices we have transport locator and then we are going to use…

SDWAN DIA Design Options Van is evolving and so as the SDWAN and so as the cloud integration with the SDWAN, because now when we are talking about new van strategy, we are talking about that how this new van or new SDWAN fabric will integrate or adopt the cloud. So it’s not only the evolution of van, but it’s the evolution and the strategy and change in the strategy for the cloud integration with the van. Why it is required, why customers are looking for this, because now, if…

App Aware Routing BFD SLA Class Let us discuss about SLA class. The overall goal of this particular session is to understand that how the Viptilla fabric inside the tunnels they are collecting the information of the applications in terms of loss, latency and jitter. And then in the upcoming session and we’ll see that how we can apply all these things inside your policy. What happened in the Vipela fabric that once your control and data plane is up by default all V edges they have their IPsec tunnels…

Multi-topology Control Policy Configuration In this section we are going to learn that how we can build and implement the control policy. So let’s see that what type of control policies we have. We can see in the slide that we can do service chaining with control policy, we can do traffic engineering. We have extranet feature that is nothing but a route leak between different types of VPN. Say, for example, VPN. Ten and VPN 20 by default, these VPN will not communicate to each other. So you can…

Use Control Policy to Block subnet All right? So in this lab, what is the agenda? We have that we are going to create the policy to block certain routes to get advertised, correct? So if I go to branch number one v edge number two and let me show you the configuration here. So in this I have one. So here you can see I have an interface called loopback 77 whose IP is 70 70 77 that is inside VPN number ten. So I can show you the…

SDWAN Policy Section One of the important section we have is section four where we have to learn about various type of policy. So we have control policy, we have data policy, we have centralized policy, we have localized policy. Now you’ll come to know in upcoming sessions that control policy is nothing much, that is very much close to routing policy or you can tell control policy, routing policy. Now this control policy that we are going to build over vs. Smart that is going to provide us full…

OSPF Part 02 After attaching the template again, we got an error that due to some firewall issue it is not working. So what we can do is that we can go to that DC One and then the VPN template and we can go and improve that template. So I have created the copy we can see actually we should go and check the template that is related to VPN Ten. So what was the main template we have? This is the template we are looking for. Just go…

VRRP Configuration Let us do the VRRP configuration. So what I will do here that in this section I will go and log into the V manage from Manage I will go and edit the interface configurations. Because inside the interface we have the VRRP configuration. So we have say for example VR RP ten related to VPN 1020 and 40 we have different Verses. So let’s go here and we are inside the branch one. Say for example VPN ten interface. Here I’ll go, I have option, I can…
