IPv6 ND Host-Router Discovery Functions
Connecting individual networks together creates internetworks. The devices that are responsible for this connection of networks are routers, which send data from one network to the next. A host must rely on a router to forward transmissions to all devices other than those on the local network. For this reason, before a host can properly use an internetwork, it needs to find a local router and learn important information about both the router and the network itself.
