Getting Started with Cisco ACI with ACI Simulator.

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.

GNS3 LAB Cisco : Nexus 9000v Control-plane based VxLAN BGP-EVPN Bridging Config and Verification.

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.

GNS3 Cisco LAB : Nexus 9000v NxOS VxLAN Lab and concept.

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.

GNS3 LAB Cisco : EVPN (BGP/MPLS) IRB (integrated routing and bridging) Configuration and Verification.

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.

GNS3 Lab Cisco : EVPN Multihome Concept and Configurations

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

GNS3 Cisco Lab : SRTE(Segment Routing Traffic Engineering) WECMP(weighted ECMP) configuration on Cisco IOS-XR and IOS-XE routers.

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.

GNS3 Cisco Lab : Segment routing Traffic engineering(SRTE) explicit and dynamic path configuration on IOS-XR.

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.

GNS3 LAB: Segment Routing Configuration on Cisco IOS-XE and IOS-XR routers.

This blog is very close to my heart because this is the first one where the lab is done on my recently built remote GNS3 server. Please check my blog on how to configure GNS3 as a remote server here How to Run GNS3 in Client Server Mode Now, lets get started with Segment routing.… Read More GNS3 LAB: Segment Routing Configuration on Cisco IOS-XE and IOS-XR routers.
