Advanced IPv6 Concepts
Before we jump into the coverage of IPv6 routing protocols, we need to discuss some of the operations that are performed differently in IPv6 than in IPv4 and that includes several operations that are radically different. We’ll also discuss in the following sections some of the methods that have been developed over the past few years to ease the pain of transitioning to an IPv6 environment from one that is IPv4.
Router Advertisement
A router advertisement is part of a new system configuration option in IPv6. This a packet sent by routers to give the host a network ID ( called a prefix in IPv6) so that the host can generate its own IPv6 address derived from its MAC address.
To perform auto-configuration, a host goes through a basic three-step process:
- First, the host needs the prefix information, similar to the network portion of an IPv4 address, to configure its interface, so it sends a router solicitation (RS) request for it. This RS is then sent out as...
