15
Use the following steps:
R3#c?
clear clock configure connect copy
R3#c
16
show running-config and write terminal would be used.
17
show startup-config and show config would be used.
18
CDP stands for Cisco Discovery Protocol.
19
The primary metric is a counter of timer ticks. If two routes to the same network tie with
the ticks metric, the hop count is considered.

GNS stands for Get Nearest Server. Any router can respond to GNS requests, which are
issued by clients. Both R2 and R3 will reply by default; R2's response is unlikely to be
used because its GNS delay will ensure that its reply is slower than the server on the same
Ethernet.
Scenario 9-2
This scenario uses the familiar Frame Relay network with three routers and a full mesh of
virtual circuits. Some planning exercises begin the scenario (Scenario 9-2, Part A), followed by
configuration (Scenario 9-2, Part B). Finally, a series of questions, some based on show and
debug command output, finish the scenario (Scenario 9-2, Part C).
Scenario 9-2, Part A--Planning
Your job is to deploy a new network with three sites, as shown in Figure 9-3. The choice to use
Frame Relay, as well as the product choices, have already been made. For Part A of this
scenario, perform the following tasks:
1
Subnet planning has been completed. Before implementation, you are responsible for
providing a list for the local LAN administrators defining the IP addresses that they can
assign to hosts. Using Table 9-5, derive the subnet numbers and broadcast addresses, and
define the range of valid IP addresses. A static mask of 255.255.255.192 is used on all
subnets.
2
PC11 and PC12 use different IPX encapsulations, as do PC21 and PC22. Figure 9-4 shows
the types of headers used by each PC. Plan the encapsulation types to be used, including
the correct keywords used in the IOS.
3
Plan the IPX network numbers to be used. Use Table 9-6 to record the information.
