Policy-based Tunnel Selection (PBTS) on Cisco IOS-XR
Recently, I had to look after PBTS on Cisco ASR9K platform and faced some issues, here are some results about my tests.

RPKI: BGP Security Hammpered by a Legal Agreement
Resource Public Key Infrastructure (RPKI) is a relatively new standard for establishing BGP route origination. I wrote a brief introductory article here. Apologies for the self-promotion, but rather than rehash the basics here, I raise another issue that needs community attention: ARIN’s Relying Party Agreement (RPA: PDF link). Having said that, some basics are needed. […]

Show 215 – SDN Training & Certifications with Wendell Odom
Software defined networking (SDN) has arrived in the form of vendor released products. If you follow this show, you know that these products are largely incompatible. Certainly there’s no “one size fits all” when it comes to SDN technologies today. In SDN’s awkward tween years, what are network engineers trying to stay current to do? […]

NG mVPN-Control Plane Overview
In this post we will be exploring the shortcomings of MVPN (Draft Rosen/RFC 6037), with a focus on how NG-MVPN technologies address these limitations. Why NG-MVPN?
