EUI-64 address

“

- [Instructor] We know that an IP version 6 address is 128 bits in length. And there are times when a device, like a router or a PC might want to generate the last 64 bits of its own address. Whether that address is going to be used by the device to communicate on the network or maybe that address is going to be used as that device's link-local address to communicate just on its local link. Well, the good news is we can use an approach called EUI-64 to have a device self-generate the last 64 bits of its IP version 6 address. And later in this chapter, we'll see how this is used for a device to automatically give itself an IP version 6 address it can use to communicate on the network but in this video, I want to show you how we could use this approach to calculate the last 64 bits of a link-local address. Specifically, R1 has interface gig 0/1 with a MAC address of 0015.2BE4.9B60. We want to use that unique MAC…
