The Best MPLS Lecture on the Net
The title says it all. Professor Karandikar gives two amazing lectures on MPLS and MPLS-TE that most engineers should hope to know cold. I watch it probably once every few months. Not saying much for my memory these days. It is an amazing amount of material delivered very precisely. Great stuff! I added some figures to look over while watching the …
MPLS VPLS configuration with Juniper JunOS.
Posting a Juniper VPLS how-to on a couple of J-series routers. Have been pretty SDN focused lately so wanted to get some real stuff in for a post. Docs on JunOS VPLS can be shaky so nothing like a couple real configs to plugin your address in the lab if having problems with L2 VPNs. This includes MPLS VPLS configuration …
A No-Brainer use case for MPLS in the Enterprise for PCI Compliance
One easy peazy reason to but a financial business case to deploying MPLS in most Enterprise networks, especially research and education (R&E) or merchant site networks is for Payment Card Industry (PCI) compliance. PCI DSS v2.0 soon to be v3.0 is on of the few technological security documents that clearly states the requirements. Path Isolation is very clear for the network architect …
Basic MPLS/VPN with Cisco IOS
This is a quick tutorial for basic MPLS/VPN with Cisco IOS configuration. The tutorial exemplifies basic PE to P to PE configuration on three Cisco 7200s running in GNS3 with IOS. R2 is configured as a route reflector P node and R4, R6 and R3 are PE node route reflector clients. The IGP is OSPF with R2 as the ABR. Loopback1 …
The MPLS and transport roles merge
The Juniper PTX in 2011 was a pretty bold merge of the OTN and MPLS functionality into one box. They are marketing it as the “Converged Supercore” http://www.juniper.net/as/en/dm/supercore/. As the debate of packet vs. circuit switched networks has clearly been won by the packet side of the house. Arguably the the increasing demands of service provider bandwidth for triple play …
MVPN Multicast with Multi-Protocol BGP MPLS VPN on Cisco IOS
Below assumes you have the basic MPLS transport setup. MVPN or multicast vpn is deployed on Cisco gear using Multicast Distribution Trees (MDT). This information is encapsulated in the MPBGP MPLS sessions to be distributed into label switch paths (LSPs) for forwarding. The following code will produce a basic functioning Cisco IOS MDT multicast environment. A tutorial for that can …
How to deploy MPLS VPN’s on Cisco gear
There is no easier way to simplify your enterprise routing and path isolation than implementing MPLS/VPNs RFC 4364. Label Distribution Protocol (LDP) is the transport method to insert a label into the header to be forwarded down the Label Switch Path (LSP) by the Label Switch Router (LSR) Most routers past the SOHO market support MPLS in hardware. On the …
If you are interested in OpenFlow and SDN, in the next few weeks I will humbly be publishing a book in which I co-authored with my friend and networking superstar, Greg Ferro. Whether we are ready or not, SDN is on its way. It is a 20 year disruption that needs leaders from the community to help determine networkings future. The book is titled The OpenFlow Book: Network Engineers Introduction to OpenFlow and Its Usage. If interested, take a look or even sign up for a notification for when it will be published. Thanks!
