Dynamic routing in IPv6
The principles that govern dynamic routing in IPv6 are fundamentally the same as those in IPv4. However, it’s crucial to understand that while IPv6 operates similarly to IPv4 in terms of routing, it utilizes a distinct routing table and process.
When a router receives a packet, the routing scheme of the packet determines how the traffic will be routed. If the packet is using the IPv4 scheme, the router will refer to the IPv4 routing table to determine the best path for the packet. This table contains all the necessary information about network paths within the IPv4 framework. See Dynamic routing for more information.
Conversely, if the router receives a packet with an IPv6 address, it will consult the IPv6 routing table. This separate table contains all the relevant information for routing within the IPv6 framework.
In essence, while both IPv4 and IPv6 use similar methods for routing packets, they each have their own dedicated processes and tables to ensure efficient and accurate routing.
