protocol? (Choose two.)
the requirement to periodically flood link-state packets to all neighbors
a change in the topology

propagate a static default route.
17 What is different between IPv6 routing table entries compared to IPv4 routing table entries?
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.
IPv6 routing tables include local route entries which IPv4 routing tables do not.
By design IPv6 is classless so all routes are effectively level 1 ultimate routes.

Visit
The router has built its link-state database.

route in a router's routing table? (Choose two.)
contain subnets
contain a next-hop IP address
Visit

21 A destination route in the routing table is indicated with a code D. Which kind of route entry
is this?
a route dynamically learned through the EIGRP routing protocol
