Question 69
Question
What is different between IPv6 routing table entries compared to IPv4 routing table entries?
Answer
-
IPv6 does not use static routes to populate the routing table as used in IPv4.
-
The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix.
-
By design IPv6 is classless so all routes are effectively level 1 ultimate routes.
-
IPv6 routing tables include local route entries which IPv4 routing tables do not.
