In the MPLS Traffic Engineering (TE) IS-IS Configuration lesson and other MPLS TE lessons, I use IS-IS as the IGP on the TE routers. In this lesson, we’ll use OSPF instead. I’ll walk you through the entire configuration, but because I already explained in detail how to configure an MPLS TE network step-by-step, I’ll only focus […]

Web application penetration testing is a security review method designed to uncover vulnerabilities […]
In the introduction to MPLS Traffic Engineering (TE) lesson, I gave a short overview of how MPLS TE uses RSVP-TE (Resource Reservation Protocol – Traffic Engineering). In this lesson, we’ll take a closer look. RSVP-TE is a signaling protocol and an extension of RSVP. RSVP-TE uses a soft state to manage its resource reservation states. This […]

TD Ameritrade and Charles Schwab are the latest firms facing suits, this time in the US District Court in Nebraska by David Schultz, who on Aug. 23, filed […]
SVG has so many tricks up its sleeve. It’s really a full-featured drawing API literally designed for the web, but few of us really truly understand it nor reach for it enough. Heck, I even wrote a book about it, and I don’t. At the time, just getting people to use SVG for icons felt […]
In this lesson, I’ll explain how to configure MPLS VPN per VRF TE tunnels. If you haven’t configured MPLS VPN over TE tunnels before, look at our MPLS VPN over MPLS TE tunnels first. Building a TE tunnel for customer VRFs doesn’t make much sense because of scalability issues. If you have more traffic in a […]
