Guide 1  Junos MPLS and VPNs, Revision 10.a EDU-JUN-JMV-10.a Junos MPLS and VPNs, Revision 10.a. Student Guide, Detailed Lab Guide, High-Level Lab Guide, and Lab Diagrams. This five-day course is designed to provide students with MPLS- based virtual private network (VPN) knowledge and configuration examples. The course includes an overview of MPLS concepts such as control and forwarding plane, RSVP Traffic Engineering, LDP, Layer 3 VPNs, next-generation multicast virtual private networks (MVPNs), BGP Layer 2 VPNs, LDP Layer 2 Circuits, and virtual private LAN service (VPLS). This course also covers Junos operating system- specific implementations of Layer 2 control instances and active interface for VPLS. This course is based on the Junos OS Release 10.3R1.9. Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and in device operations. Guide 2  Junos Multicast Routing, Revision 11.a EDU-JUN-JMR-11.a Junos Multi

By Jeff Doyle I explained in the  previous post  how the RSVP-TE Explicit Route Object (ERO) specifies the path of an MPLS LSP by means of a sequenced list of Label Switching Routers (LSRs) that the LSP must pass through between the ingress and egress LSRs. RSVP-TE uses the path described in the ERO to signal and set up the LSP. That’s the foundation of MPLS traffic engineering: The ability to set up a path that is different from what the local IGP considers the optimum path between the ingress and egress, as shown in  Figure 1 . In fact, different LSPs between the same two endpoints can take different paths. It all depends on what constraints  you place on each LSP. For example, each LSP might require different amounts of reserved bandwidth or might be constrained by the types of links they can use. The question we were left with at the end of the previous post was: How is the ERO created at the ingress? You can of course manually configure the ERO for each LSP at each i

I was trying to use the JNCIA and JNCIS study guides but looks like there are some changes between JunOS 8.x and 11.x in the way how static LSPs should be configured. There is an interesting post on 0x8847.net about the static LSPs that I am going to try. http://www.0x8847.net/2011/08/juniper-mpls-vpn-static-lsp/

I got my HTC ONE X few days ago and I LOVE it.  Probably Samsung S3 or Iphone5 will be better but it's really amazing how far HTC went with this product. The shapes of the device and the user experience are outstanding. I thought the 32Gig internal flash want be enough but I still have a lot of space. The music sounds really good (the head-phones that are coming with the phone look cheap as well as the package). The battery is 1800MHA and the power consumption is around 10% per hour with my usage (e.g web browsing and playing with the application). I didn't want to comment the CPU but because someone opened the discussion couple of days ago how Qualcomm are better etc. It's true. S4 is better than Tegra 3 but the difference is really small between these two CPUs. What you will get with Tegra 3 is access to the exclusive games in the Nvidia Tegra Zone (I don't play games that much but it's sounds cool) HTC Sense 4. It's really nice overall of Android UI. D
