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. You must remember MPLS… Read More GNS3 Cisco Lab : Segment routing Traffic engineering(SRTE) explicit and dynamic path configuration on IOS-XR.

GNS3 LAB : LFA(Loop free alternate) and RLFA(Remote-LFA) on Cisco Routers.

Convergence time is a problem that humankind is trying to resolve since the day IGPs were discovered. Every vendor keeps on pushing less convergence time. With low “hold time” intervals we somehow manage to decrease the convergence time but this also has a limit, and the chances of raising bigger problems increase when we keep… Read More GNS3 LAB : LFA(Loop free alternate) and RLFA(Remote-LFA) on Cisco Routers.
