In this post I'm going to walk through how we can configure basic multicast routing using PIM Sparse-Mode. I'm going to walk though how the multicast traffic flows from the source to the receiver, what's the role of the Rendezvous Point (RP), how are the…

In this lab I'm going to use the same simple topology which I used in this post. Except that we're going to take a look how we can turn a Cisco IOS router into a stateless/stateful DHCPv6 server, what's the difference and how we can…

I'm going to configure a policer to restrict and meter the traffic coming from Customer 1 on one of the PE router. The topology I'm using is the same I've used in the MPLS L2VPN post. Except this time I configured Customer 1 in a…

In this lab we're going to implement IPv6 FHS with Router Advertisement Guard and IPv6 Snooping and in the following post I'll show how to configure DHCPv6 Guard. We configure IPv6 FHS on the access switch between the end hosts and the routers in the…
