Hello all, I've read already a couple of RFCs and books to familiarize myself with IPv6. I'm struggling with the following: Neighbor discovery is used to find out the corresponding Layer-2 address to a given IPv6 unicast address ( similar to the ARP process in IPv4). On the other hand I have learned that all global aggregatable unicast addresses have to use the EUI-64 format for the interface ID. At least in a Ethernet (I think this is the majority of the LANs today) this EUI-64 ID is derived from the MAC address in an reversible way. (Simply adding/removing 0xFFFE in the "middle"). So my question is why do I need the ND in a LAN in order to do the address resolution ??? I know that there must be a simple reason, but I don't know it.
Is anyone able to sched some light into this ? Thanks very much Matt Mit freundlichen Grüssen / with kind regards Matthias Huber Siemens AG I&C Training Institute CCSI CCNA ICM CA VZ TI A5 Phone +49 89-722-34051 Baierbrunnerstrasse 28 Fax +49 89-722-61684 81359 Munich/Germany Mail mailto:[EMAIL PROTECTED] -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
