  Task 3 :- Configure host ip given topology.

give IP address 192.168.1.2 as we give in pc or laptop ..  same as in server   100.1.1.2

--------------------------------------------------------------------------------------------------------------

  


Task 4 :- Configure RIP protocol.


R1

R1(config)#
R1(config)#router rip
R1(config-router)#

 Task 5 :- Check communication in  host to server.

PC#ping 100.1.1.2  !! this is Server ip !!

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 100.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 64/85/100 ms\

--------------------------------------------------------------------------------------------------------------

 Task 6 :- Enable DYNAMIC  NAT.

R1

 First create Access list and given network 
R1(config)#access-list 101 permit ip 192.168.1.0 0.0.0.255 any

 now Create NAT Pool

 R1(config)#ip nat pool ccna 172.16.1.1 172.16.1.4 netmask 255.255.255.0




 now create Dynamic NAT
R1(config)#ip nat inside source list 101 pool ccna overload

apply on interface 

R1

R1(config)#interface fastEthernet 0/0
R1(config-if)#ip nat inside

R1(config)# interface fastEthernet0/1
R1(config-if)#ip nat outside
