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 like VPLS, Vxlan with the help of BGP address… Read More GNS3 LAB Cisco : BGP-EVPN Single Home Configuration
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.
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.
Here is a quick example of configuring ISIS between two cisco IOS-XR devices. The configuration is a little different than how we do on Cisco IOS or IOS-XE devices, however, theoretically, it is exactly the same so it doesn’t take much to understand and learn the configuration. So let’s quickly jump to the configuration. Configuration… Read More How to configure ISIS on Cisco IOS-XR
