Configure a static route to the adjacent LAN, LAN-A to LAN-B. Use the IP addresses provided in Table 1. You will be asked to verify that the computers in your LAN can ping the neighbor LAN. Note that a serial interface is being used to interconnect the LANs. You are configuring routing for both 192.168.20.0 and 172.16.75.0 networks. A subnet mask of 255.255.255.0 is being used. Use 1536000 for the clock rate on the serial link (DCE interface).

Table 1 Computer IP Addresses, Subnet Masks, and Gateway Addresses





1. Configure the gateway address for your LAN routers (R1 and R2) according to the

addresses provided in Table 1. You will also need to enable the interfaces. List the commands

used to configure the IP addresses and the subnet mask for your gateway, and list

the command used to enable the interface.

2. Configure the host name for your routers; R1 should be renamed LAN-A and R2 should

be renamed LAN-B. List the router prompts and commands used to configure the

router’s host name.

3. Configure the router interface’s serial IP addresses and subnet masks according to the

addresses specified in Table 1. Use the proper command to verify that the interfaces are

properly configured. Set the clock rate on the serial interface interconnecting the two

routers to 1536000. List the prompts and the commands used to accomplish this task.

4. Configure static routes from the LAN-A router to the LAN-

1. ```

R1# configure terminal

R1(config)# interface fa 0/0

R1(config-if)# ip address 192.168.20.250 255.255.255.0

R1(config-if)# no shutdown

R2# configure terminal

R2(config)# interface fa 0/0

R2(config-if)# ip address 172.16.75.250 255.255.255.0

R2(config-if)# no shutdown

```



2. ```

R1# configure terminal

R1(config)# hostname LAN-A

LAN-A(config)#

R2# configure terminal

R2(config)# hostname LAN-B

LAN-B(config)#

```



3. ```

LAN-A# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

LAN-A(config)# interface serial 0/0/0

LAN-A(config-if)# ip address 10.10.100.1 255.255.255.0

LAN-A(config-if)# clock rate 1536000

LAN-A(config-if)# no shut

LAN-A(config-if)#







LAN-B#

LAN-B# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

LAN-B(config)# interface serial 0/0/1

(Pass-by-Value vs. Pass-by-Reference) Write a complete C++ program with the two alternate functions specified below, each of which simply triples the variable count defined in main. Then compare and contrast the two approaches. These two functions are

a) function tripleByValue that passes a copy of count by value, triples the copy and returns the new value and b) function tripleByReference that passes count by reference via a reference parameter and triples the original value of count through its alias (i.e., the reference parameter).
