Routers configured with dynamic routing protocols such as OSPF or EIGRP must send and receive routing protocol messages with their directly connected neighbors. The routers exchange messages between neighbors on the same subnet. These messages are always sent from the router’s source IPv4 address. Link-local IPv6 addresses are perfect for this purpose. The address also… Read more

After a client receives a Stateless Address Autoconfiguration (SLAAC) message, often via a stateless Router Advertisement (RA), it must generate its Interface ID. Unlike stateful DHCPv6, SLAAC provides the prefix portion (typically /64) from the RA, while the client autonomously creates the 64-bit Interface ID. This ID can be derived from the MAC address using… Read more
