  • Understand how Aruba ARMizes your WLAN for sure!
    Presenting ARM In this post, that is a part of a serie of post that discuss how Wlan to radio ressources management, we talk of Aruba way of doing it. The figure shows a simple wlan network of 6 AP or access points. This is heatmap showing that radio signal is very strong (in red)
  • Understand RIP Routing Timers All in One Shot!
    This post is part of a series of posts about dynamic routing protocols and especially RIP. We’ll try to get a deep understanding of its operation and function as an introductory to dynamic routing logic in general. You’ll see that what we think easy may hide an incrementing complexity… a little introduction Berfore we start
  • DUAL route FSM Processing of EIGRP Queries
    This blog is a part of series of posts about EIGRP routing protocol. Let’s recall that EIGRP is one of the so called IGP routing protocols. IGP stands for interior routing protocols as opposed to EGP or exterior routing protocols. In addition EIGRP is a hybrid as it borrows some similiarities to distance-vector and link-state
  • Point-to-Point OSPF Network Operation over a LAN that connects multiple routers
    What happens when LAN interfaces are configured as point-to-point network type OSPF interfaces instead of default broadcast type? And more than 2 ospf routers are present on this media? Let’s test this on network (R1, R2, R3): Routers are Cisco 7206VXR GNS3 emulated and run C7200 ADVENTERPRISEK9-M IOS version 15.3(3)XB12. They are configured as: R1
  • VPNv4 BGP AS-Override Feature into play!
    Let’s put into play AS-Override feature in BGP: see when it applies and how it works. First, AS-Override feature applies to sites that have the same AS number but are linked by another different domain with different AS number, as in the next figure. In our example AS number 1 has neighborship (E-BGP links) to
