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 : MPLS TE( Traffic-Engineering) FRR (fast-reroute) Link Protection.

Hello folks, In continuation of my previous blog on MPLS TE configuration, I have setup fast-reroute for MPLS TE tunnel so that if a designated primary link fails then the tunnel will take up the alternate path and the traffic loss will be avoided. Please check my previous blog for basic MPLS TE config in… Read More GNS3 Cisco LAB : MPLS TE( Traffic-Engineering) FRR (fast-reroute) Link Protection.
