Recently, I have started my data center journey and was looking for something which can give me firsthand Cisco ACI experience. For ACI you need a lot of physical gear and the kind of lab I do it is totally impossible for me to practice something like this. So I looked for a virtual method… Read More Getting Started with Cisco ACI with ACI Simulator.
I wrote few blogs on BGP EVPN and also on VxLAN earlier. My previous blogs were focused on IOS-XE and IOS-XR devices, recently I have started my Data Center journey and hence I wanted to do some labs on Nexus devices as well and what better place than GNS3 for this ? I got to… Read More GNS3 LAB Cisco : Nexus 9000v Control-plane based VxLAN BGP-EVPN Bridging Config and Verification.
I have written a few blogs earlier on VxLAN. You can check them in the below links. ASR1000 : VxLAN Unicast mode Configuration and Verification ASR1000: Cisco Vxlan Multicast Mode Configuration and Verification Since then VxLAN has changed a lot and I am planning to write a series of articles on VxLAN and EVPN on… Read More GNS3 Cisco LAB : Nexus 9000v NxOS VxLAN Lab and concept.
So far we have seen EVPN single home and EVPN multihome setup and configuration with Cisco csr1000v router. You can find the links for those posts below. EVPN -Single home GNS3 LAB Cisco : BGP-EVPN Single Home Configuration EVPN -Multi homeGNS3 Lab Cisco : EVPN Multihome Concept and Configurations Note : As per Cisco docs… Read More GNS3 LAB Cisco : EVPN (BGP/MPLS) IRB (integrated routing and bridging) Configuration and Verification.
Introduction: This article is focused on multi-homed EVPN setup that I have prepared in below network topology. One of the biggest advantage with EVPN that we get is multi-homing with it. Earlier with VPLS we did not have multi-homing integrated with the protocol. With multi-homing we can have one CE connected to two PE router… Read More GNS3 Lab Cisco : EVPN Multihome Concept and Configurations
Please Subscribe to my YouTube channel for regular updates. Hi Friends, After putting alot of efforts and trying different devices I was finally able to configure EVPN on GNS3 and so far it is working like a CHARM!! Follow the blog for complete story. EVPN is a service which provides control plane for the protocols… Read More GNS3 LAB Cisco : BGP-EVPN Single Home Configuration
If you have ever tried to setup something similar to production in you network lab then you might have come across this problem that you don’t have enough routes in the routing table. This can be solved easily with traffic generators like Ixia/Spirent/Pagent etc, but you may not be having this in your home lab.We… Read More Script : Python Script to advertise routes by creating Loopback interfaces
This is a quick nugget kind of blog where we will see the configuration and working of the SRTE WECMP on IOS-XR device. We know how ECMP works basically if we have multiple paths available then we will use those paths to load balance the traffic and this is done in SRTE by default. With… Read More GNS3 Cisco Lab : SRTE(Segment Routing Traffic Engineering) WECMP(weighted ECMP) configuration on Cisco IOS-XR and IOS-XE routers.
Have you checked my previous blogs on segment routing ? You can find them here : GNS3 LAB: Segment Routing Configuration on Cisco IOS-XE and IOS-XR routers. GNS3 LAB Cisco : Segment Routing traffic engineering configuration on IOS-XE routers. In this blog, I will discuss about the explicit path SRTE policy. You must remember MPLS… Read More GNS3 Cisco Lab : Segment routing Traffic engineering(SRTE) explicit and dynamic path configuration on IOS-XR.
