Task 1:
R2(config)# ip access-list standard XLATE //Note: The name of the ACL may be different so please check carefully! R2(config-std-nacl)#permit 10.2.3.3
R2(config-std-nacl)#permit 192.168.3.1
R2(config-std-nacl)#permit 10.1.3.11 R2(config-std-nacl)#exit
R2(config)# interface e0/1 R2(config-if)#ip nat inside R2(config-if)#exit R2(config)#interface e0/0 R2(config-if)#ip nat outside R2(config-if)#exit
R2(config)#ip nat pool test_pool 10.10.10.1 10.10.10.254 netmask 255.255.255.0 R2(config)#ip nat inside source list XLATE pool test_pool


Note: This task requires to configure a dynamic one-to-one, not one-to-many so we don’t use the keyword “overload”.


Task 2:
R1 has been configured an DHCP Server already so we just need to configure DHCP Client on R3. R3(config)#interface e0/2
R3(config-if)#ip address dhcp

Wait a moment and we will see E0/2 of R3 is assigned the IP address 10.1.3.11 with the following message:

%DHCP-6-ADDRESS_ASSIGN: Interface Ethernet0/2 assigned DHCP address 10.1.3.11, mask 255.255.255.0, hostname R3

We can verify with the command “show ip interface brief” on R3: R3(config-if)#exit

R3(config)#exit

R3#show ip interface brief

Interface ...	IP-Address	OK? Method Status	Protocol
Ethernet0/2	10.1.3.11	YES unset up	up

-> We see E0/2 has been assigned the IP address 10.1.3.11.


Task 3:

R1#config t

R1(config)#ntp master 1 //Configure R1 as an NTP server

Note: In this version, interface E0/2 of R1 was assigned the IP address of 10.1.3.1/24. Configure R2 as the NTP client (not NTP peer):

R2#config t
R2(config)#ntp server 10.1.3.1
