CHAPTER 14 - Dynamic Routing

1980s

Dynamic routing protocols have been used in networks since the late ____s

Routing Protocols

are used to facilitate the exchange of routing information between routers.

Dynamic

The purpose of _______ routing protocols includes:

▪ Discovery of remote networks

▪ Maintaining up-to-date routing information

▪ Choosing the best path to destination networks

▪ Ability to find a new best path if the current path is no longer available

Data structures

component of drp. Routing protocols typically use tables or databases for its operations. This information is kept in RAM.

Routing protocol messages

component of drp. Routing protocols use various types of messages to discover neighboring routers, exchange routing information, and other tasks to learn and maintain accurate information about the network.

Algorithm

component of drp. Routing protocols use _________ for facilitating routing information for best path determination.

no auto-summary

Similarly to RIPv1, RIPv2 automatically summarizes networks at major network boundaries by default. To modify the default RIPv2 behavior of automatic summarization, use the __ ____-_______ router configuration mode command

Subnets, masks

When automatic summarization has been disabled, RIPv2 no longer summarizes networks to their classful address at boundary routers. RIPv2 now includes all _______ and their appropriate _____ in its routing updates.

ultimate route

is a routing table entry that contains either a next-hop IP address or an exit interface.

Ultimate

Directly connected, dynamically learned, and link local routes are ________ routes.

level 1 ultimate

IPv6 is classless by design, all routes are effectively _____ _ _________ routes. There is no level 1 parent of level 2 child routes
