R2(config)#exit R2#show ntp status

Clock is synchronized, stratum 2, reference is 10.1.3.1

Task 4:
R3(config)#line vty 0 4
R3(config-line)#transport input ssh R3(config-line)#login local R3(config-line)#exit
R3(config)#username root password s3cret//Note: Please check the username and password given carefully. It may not be “root” and “s3cret” as shown here
R3(config)#crypto key generate rsa modulus 1024


Note: The command “ip domain-name xyz.com” has been configured so we don’t need to type this command again. This command must be used before the “crypto key generate rsa” command or an error will be shown.

R1# ssh -l root 10.1.3.11
Password: {please type s3cret here} Save the configuration
As the guidelines clearly stated that we have to save the configuration to NVRAM so please save all your configurations on R1, R2 and R3: R1#, R2#, R3#copy running-config startup-config
Note: Just for your information, this lab requires “Do not use NVI NAT configuration” so what is NVI NAT?

Cisco IOS Release 12.3(14)T introduced a feature called NAT Virtual Interface (NVI), which allows you to do a NAT configuration without the need to specify an interface as being an inside or an outside interface. Specifically, instead of issuing the “ip nat inside” or “ip nat outside” command in interface configuration mode, you can issue the “ip nat enable” command. Not only does this feature make configuration easier , but it also allows traffic to flow between two interfaces that would both be considered inside interfaces, from a classic NAT perspective.

Correct Answer: A
Static Routing Configuration Sim


QUESTION 1
Topology

Tasks

Connectivity between four routers has been established. IP connectivity must be configured in the order presented to complete the implementation. No dynamic routing protocols are included.

1. 
   Configure static routing using host routes to establish connectivity from router R3 to the router R1 Loopback address using the source IP of 209.165.200.230.
   
2. 
   Configure an IPv4 default route on router R2 destined for router R4.
   
3. 
   Configure an IPv6 default router on router R2 destined for router R4.
   

A. Solution

Note: A host route is an IPv4 address with a 32-bit mask

Task 1: In this task we have to configure all the static routes so that R3 can ping Loopback 1 of R1 successfully R3(config)#ip route 192.168.1.1 255.255.255.255 209.165.200.229
R2(config)#ip route 192.168.1.1 255.255.255.255 209.165.200.225
R1(config)#ip route 209.165.200.230 255.255.255.255 209.165.200.226

Verification

R3#ping 192.168.1.1

2. R2(config)#ip route 0.0.0.0 0.0.0.0 209.165.202.130

3. R2(config)#ipv6 route ::/0 2001:db8:abcd::2
