31
Define the tunneling terms transport protocol, encapsulation protocol, and passenger
protocol.
32
List the Interior IP routing protocols that have auto summarization enabled by default.
Which of these protocols allows auto summary to be disabled using a configuration
command?
33
List the interior IP routing protocols that support route aggregation.
34
Identify the command that would list all IP routes learned via RIP.
35
Identify the command(s) that would list all IP routes in network 172.16.0.0.
36
Assume that several subnets of network 172.16.0.0 exist in a router's routing table. What
must be true about those routes so that the output of the show ip route command lists
mask information only on the line that lists network 172.16.0.0, but not show mask
information on each route for each subnet?
37
True or false: Distance vector routing protocols learn routes by transmitting routing
updates.
38
Assume that a router is configured to allow only one route in the routing table to each
destination network. If more than one route to a particular subnet is learned, and if each
route has the same metric value, which route is placed into the routing table if the routing
protocol uses distance vector logic?
39
Describe the purpose and meaning of route poisoning.
40
Describe the meaning and purpose of triggered updates.
