3.1.b (iv) Autoconfig/SLAAC, temporary adresses (RFC4941) IPv6 Stateless Address Autoconfiguration (SLAAC) Utilizes 2 ICMPv6 messages to communicate the prefix to clients: Router solicitation Router advertisement note: Review the 3.1.b (iii) for a more indepth look at these messages These basically allow our host to communicate to the router and then learn the global ipv6 …

3.1.b (iii) ND, RS/RA IPv6 address resolution. In IPv4 we had arp, to facilitate layer 2 communication. In IPv6 we have ICMPv6 neighbor discovery (ND). The neighbor discovery protocol has two purposes: 1. For discovering and tracking other IPv6 hosts 2. For automatic address configuration ND uses 5 ICMPv6 messages. neighbor solicitation neighbor advertisement router …
3.1.b (ii) EUI-64 EUI-64 stands for Extended Unique Identifier, it is a way for an IPv6 host to automatically assign itself an IPv6 address via using it's mac address. EUI-64 allows us to configure the interface id part of an IPv6 address (last 64 bits) EUI-64 requires that the network part of the address …
3.1.b Identify, and troubleshoot IPv6 Addressing and Subnetting IPv6 Review: The main RFC is 2460 How many addresses do we have with IPv6? 2(128th power) IPv6 is written as hexadecimal, they are separated by colons, and each field is 16 bits in size. Thus each character in HEX = 4 bits What are the …

3.1.a (ii) ARP From within the same LAN we need a reliable way to map IP addresses to MAC addresses. The way ARP works is we send out a request which goes out as an ethernet broadcast, to all hosts on the broadcast domain. The dst mac this is sent to is ffff.ffff.ffff. This request …
3.1.a (i) Address types, VLSM For this section you should understand the basics of IPv4 addressing. We should remember that an IPv4 address is a 32bit number with a max of about 4 billion. It's written in dotted decimal notation like so 10.0.0.1 Each number separated by a decimal is 1 byte in size. …
