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

Script : Python Script to advertise routes by creating Loopback interfaces

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

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 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.
