Understanding IPv6: Solicited-Node Multicast In Action (Part 7 of 7)

Understanding IPv6: Solicited-Node Multicast In Action (Part 7 of 7)

  The last few blogs in my series on IPv6 have focused on solicited-node multicast, which provides the functionality for Neighbor Discovery in IPv6 addressing. We ended the last blog with a cliffhanger, asking, “In IPv6, how do we find the Layer 2 MAC address associated with a Layer 3 IPv6 address?”   Time to put the pieces togetherContinue Reading

Understanding IPv6: The Ping Before Solicited-Node Multicast (Part 6 of 7)

Understanding IPv6: The Ping Before Solicited-Node Multicast (Part 6 of 7)

In a previous blog, we looked at the basics of IPv6 solicited-node multicast. Going back to our Router A and Router B environment, if we sniff the wire while pinging from Router A’s IPv6 address to Router B’s IPv6 address, what will we see? Spoilers! Suffice it to say we will see some IPv6 solicited-node multicast veryContinue Reading

Understanding IPv6: Prepping For Solicited-Node Multicast (Part 5 of 7)

Solicited-node multicast: I stumbled and tripped a bunch over this one in the beginning.  Well, that isn’t 100% true. Admittedly, at first, I really just ignored it, which really got in the way of my understanding some of the fundamentals of Neighbor Discovery Protocol (NDP). But before we jump into solicited-node multicast, let’s review link-local scopeContinue Reading
