Routing table entries that begin with the letter D are learned dynamically using the EIGRP routing protocol. Static route entries on the routing table are identified with S. Directly connected route entries are denoted by the letter C.

The IPv6 destination address 2001:DB8:ACAD:E:240:BFF:FED4:9DD2 belongs to the network of 2001:DB8:ACAD:E::/64. In the routing table, the route to forward the packet has Serial 0/0/1 as an exit interface and 2682112 as the cost.

Dynamic routing protocols are used on routers to exchange route information between routers to support network communication..

Dynamic routing protocols exist to discover the network, maintain routing tables, and calculate the best path. Having low levels of routing overhead, using the path specified by the administrator, and avoiding the exposure of network information are functions of static routing.

The RIP route with the source code R is used to forward data to the destination IPv6 address of 2001:DB8:CAFE:4::A. This route has an AD value of 120.

With the implementation of dynamic routing protocols, RIP summarizes networks at classful boundaries by default. To configure a router to automatically summarize networks, the auto-summary command would be used.

A supernet route is a route that has a network address with a subnet mask that is less than the classful equivalent for the network. If the 192.168.1.0 network address was using a /16 (255.255.0.0) mask, this would be less than the classful equivalent for a 192.168.1.X network address. A summary address is an example of a supernet route.

The Cisco IP routing table is not a flat database. It has a hierarchical structure that is used to expedite the lookup process when locating routes and forwarding packets. The terms ultimate route, level 1 route, level 1 parent route, and level 2 child routes describe the operation and the hierarchical nature of the routing table contents.

Even though RIP has a higher administrative distance value (less trustworthy), the best match is the route in the routing table that has the most number of far left matching bits.

In IPv6, all routes in the routing table are level 1 ultimate routes and contain a next-hop IPv6 address or exit interface or both.When a match is found, the traffic is forwarded.

Directly connected and local routes are automatically created whenever an interface is configured with an IP address and activated.

Dynamic routing is simpler to configure than static routing in larger networks. Static routing does not scale well as networks grow in .

RIP configuration on a router should contain network statements for connected networks only. Remote networks are learned from routing updates from other routers.
