Background / Scenario
This activity requires you to configure the R2 router using the settings from the Addressing Tabular array and the specifications listed. The R1 router and the devices continued to it have been configured. This is a comprehensive review of previously covered IOS router commands. In Part 1, y'all will complete basic configurations and interface settings on the router. In Part 2, you will use SSH to connect to the router remotely and utilise the IOS commands to retrieve information from the device to answer questions well-nigh the router. For review purposes, this lab provides the commands necessary for specific router configurations.
Instructions

o. Save the running configuration to the startup configuration file.
R2# copy running-config startup-config Pace 3: Verify network connectivity.
a. Using the control line at PC3, ping the IPv4 and IPv6 addresses for PC4.
Were the pings successful?
Yes
b. From the CLI on R2 ping the S0/one/1 address of R1 for both IPv4 and IPv6. The addresses assigned to the S0/ane/i interface on R1 are:
IPv4 address = 10.0.3.1
IPv6 accost = 2001:db8:acad:three::one
Were the pings successful?
Aye
From the command line of PC3 ping the ISP address 209.165.200.226.
Were the pings successful?
Yes, the PC is using the default gateway router to forwards the traffic.
From PC3 attempt to ping an address on the ISP for testing, 64.100.one.i.
Were the pings successful?
No, routing has not been configured on the router so only local connected networks are accessible. No default route is prepare on router R2.
c. From the control line of PC3 open an SSH session to the R2 G0/0/0 IPv4 accost and log in as SSHadmin with the password 55Hadm!n.
C:\> ssh -l SSHadmin 10.0.4.1 Countersign:
Was remote access successful?
Yep
Part 2: Display Router Information
In Function 2, you will use evidence commands from an SSH session to call back data from the router.
Step one: Establish an SSH session to R2.
From the control line of PC3 open an SSH session to the R2 G0/0/0 IPv6 accost and log in every bit SSHadmin with the password 55Hadm!n.
Step 2: Retrieve of import hardware and software information.
a. Use the show version control to reply questions about the router.

Configuration register is 0x2102 What is the name of the IOS image that the router is running?
Epitome version isr4300-universalk9.03.xvi.05.Due south.155-3.S5-ext.SPA.bin.
How much non-volatile random-access memory (NVRAM) does the router accept?
32768K bytes of NVRAM.
How much Flash retentivity does the router have?
3223551K bytes of wink memory.
b. The show commands oft provide multiple screens of outputs. Filtering the output allows a user to display certain sections of the output. To enable the filtering control, enter a pipage (|) character later on a bear witness control, followed by a filtering parameter and a filtering expression. Yous can match the output to the filtering statement by using the include keyword to display all lines from the output that contain the filtering expression. Filter the show version command, using show version | include register to respond the following question.
R2# show version | include register Configuration register is 0x2102
What is the boot procedure for the router on the next reload?
Answers may vary. In about cases (0x2102), the router will undergo a normal kicking, load the IOS from the Flash memory, and load the startup configuration from the NVRAM if present. If the config annals is 0x2142, the router will bypass the startup config and brainstorm at the user-mode command prompt. If the initial boot fails, the router goes into ROMMON way.
Step 3: Display the running configuration.
a. Use the show running-config control on the router to answer the following questions filtering for lines containing the discussion "password".
R2# show running-config | include password service password-encryption password seven 0822455D0A16 countersign 7 0822455D0A16 How are passwords presented in the output?
Passwords are encrypted due to the service password-encryption command.
b. Use the show running-config | begin vty command.
R2# show running-config | begin vty line vty 0 iv exec-timeout 6 0 password 7 0822455D0A16 login local send input ssh What is the upshot of using this command?
A user receives the running configuration output beginning with the line that includes the outset instance of the filtering expression.
Annotation: A more specific control would be show running-config | section vty; however, the current version of Package Tracer does not support the department filtering command.
Footstep four: Display the routing tabular array on the router.
Apply the show ip route command on the router to reply the following questions.
R2# evidence ip route Codes: L - local, C - continued, S - static, R - RIP, Yard - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter surface area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, Due east - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static road, o - ODR P - periodic downloaded static road Gateway of concluding resort is non set 10.0.0.0/8 is variably subnetted, half dozen subnets, 2 masks C x.0.3.0/24 is directly connected, Serial0/one/0 L x.0.3.2/32 is straight connected, Serial0/1/0 C ten.0.iv.0/24 is direct connected, GigabitEthernet0/0/0 L 10.0.four.1/32 is straight connected, GigabitEthernet0/0/0 C 10.0.v.0/24 is direct connected, GigabitEthernet0/0/1 Fifty 10.0.5.1/32 is straight connected, GigabitEthernet0/0/ane 209.165.200.0/24 is variably subnetted, two subnets, 2 masks C 209.165.200.224/30 is directly connected, Serial0/1/1 L 209.165.200.225/32 is direct connected, Serial0/1/1Questions: What code is used in the routing table to signal a directly connected network?
The C designates a direct connected subnet. An L designates a local interface. Both answers are correct.
How many route entries are coded with a C code in the routing table?
Footstep 5: Display a summary list of the interfaces on the router.
a. Use the show ip interface brief control on the router to answer the post-obit question.
R2# show ip interface brief Interface IP-Accost OK? Method Status Protocol GigabitEthernet0/0/0 10.0.4.1 YES manual upwards up GigabitEthernet0/0/1 10.0.5.i YES manual up up Serial0/1/0 x.0.3.2 YES transmission up upwardly Serial0/i/one 209.165.200.225 Aye manual upward up Vlan1 unassigned YES unset administratively downward down What control changed the status of the Gigabit Ethernet ports from administratively downwards to upwardly?
no shutdown
What filtering command would y'all use to display only the interfaces with addresses assigned?
testify ip interface brief | exclude unassigned
b. Utilize the bear witness ipv6 int brief control to verify IPv6 settings on R2.
R2# show ipv6 interface brief GigabitEthernet0/0/0 [upwards/up] FE80::2:A 2001:DB8:ACAD:4::1 GigabitEthernet0/0/ane [upwards/upward] FE80::2:B 2001:DB8:ACAD:5::ane Serial0/1/0 [upward/upwardly] FE80::one:C 2001:DB8:ACAD:3::2 Serial0/1/1 [up/up] FE80::1:D 2001:DB8:FEED:224::1 Vlan1 [administratively down/down] Unassigned What is the meaning of the [upward/up] part of the output?
The [up/up] status reflects the Layer i and Layer 2 status of the interface and does non rely on Layer 3 for condition.
