Configuring static MPLS TE tunnels can be a highly unmanageable task if the number of PE grows. On top of that, you also need to manage FRR backup tunnels, which is only going to add complexity. Take an example of the ISP that has 100 PE routers deployed. For 100 PE routers, if you need… Read More Cisco Dynamic MPLS Traffic Engineering Tunnels (Auto-Tunnels)
Got a chance to see my other blogs on MPLS TE? I definitely recommend reading these below two because these will set the stage for this blog. MPLS TE basic config : GNS3 LAB Cisco : Quick Configuration MPLS TE (traffic engineering). MPLS TE fast-reroute link protection : GNS3 Cisco LAB : MPLS TE( Traffic-Engineering)… Read More GNS3 Cisco LAB : MPLS TE( Traffic-Engineering) FRR (fast-reroute) Node 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.
Hello folks, If you have visited my site earlier you might have seen an MPLS post related to the below network. I have been working on this network for around a month now and I plan to keep integrating different technologies in it until it breaks 🙂 (let’s see how much GNS3 on a 16… Read More GNS3 LAB Cisco : Quick Configuration MPLS TE (traffic engineering).
MPLS ping is a utility just like our old ipv4 ping in the hop to hop ip routing scenarios. The only difference is that it tells you that everything is fine in MPLS label switch path. In mpls label switch path you cannot rely on normal ping as it is possible that normal ping is working… Read More How MPLS Ping, MPLS Traceroute , MPLS Multipath trace can help in MPLS troubleshooting.
Hi Friends, In my previous MPLS posts I have covered some basics about MPLS now moving to MPLS VPN concepts, lets see how you can wrap your head around it. For mpls vpn configuration please check this blog.. MPLS VPN Config If you are a guy who comes across MPLS VPN issue once in couple… Read More GNS3 : Cisco MPLS VPN troubleshooting and Path tracing.
In Continuation to my previous MPLS articles, in this article I will discuss a rather real life example of issue and troubleshooting. You can check my previous posts on MPLS here. 1- MPLS Basic configuration and MPLS QOS 2- MPLS QOS 3- MPLS Basics and Beyond Concepts… Problem : In the below network MPLS VPN… Read More GNS3 LAB : Cisco MPLS troubleshooting trouble ticket #1
Introduction: Hi Friends, In continuation to my previous post on MPLS (check out for basic mpls config and working), in this post I will be taking a further deep dive and cover other aspects like some crucial concepts and troubleshooting methods. For this I have built up a topology including ISP and and few customer… Read More GNS3 LAB: Cisco MPLS Basics and Beyond Concepts…
In this example I am going to present a very simple configuration example for advertising ipv6 prefixes over IPv4 ISP transport network. This method is called 6VPE where we do not need any dual stack configurations and the transport network doesn’t need to be ipv6 aware. The whole concept becomes possible with the help of… Read More Cisco GNS3 Lab : Advertising IPv6 address over IPv4 MPLS/BGP Network.
Hi Friends, This is going to be a short and crisp article on MVPN Profile 0. I had some posts about L2VPN and L3VPN. In those posts I have discussed about unicast between the sites over MPLS ISP backbone. You can check my L2VPN and L3VPN posts here. L2VPN L3VPN In this post I am… Read More MVPN Profile-0 (Draft Rosen) Config on GNS3
