N.B: Make sure you are saving all the commands on packet tracer file. Use: copy run start on privileged level. 1. Build a topology like the scenario. 2. There are two VLANs here, one is CSE VLAN and another one is EEE VLAN. 3. Networks: CSE- 172.16.1.0/24----VLAN ID- 10 EEE-172.16.2.0/24-----VLAN ID-15 R1 to R2- 172.16.3.0/24 R1 to R3- 172.16.4.0/24 R2 to R4- 172.16.5.0/24 R3 to R4- 172.16.6.0/24 R4 LAN- 172.16.7.0/24 IP Assign: CSE-1 PC CSE-2 PC CSE Gateway EEE-1 PC EEE-2 PC EEE Gateway R1s Interface Interface- se0/1/0- Interface- Se0/1/1- R2s Interface Interface- se0/1/0- Interface- Se0/1/1- R3s Interface Interface- se0/1/0- Interface- Se0/1/1- R4s Interface Interface- se0/1/0- Interface- Se0/1/1- R4 LAN Gateway Configuration: Step-1: Configure Trunk Ports on all switches. C&D: ALSw1: ALSw2: Step-2: Configure VTP Server and VTP Client. C&D Switch: ALSw1: ALSw2: Step-3: Assign the VLAN according to your topology. ALSw1: ALSw2: Step-4: Configure Inter-VLAN Routing on Router. R1: Step-5: Configure Router as a DHCP Server for the CSE and EEE VLAN. DHCP for CSE: DHCP for EEE: Step-6: Use OSPF Dynamic routing protocol to communicate with everyone. R1: R2: R3: R4: Step-7: Attach the Screenshots of PCs while they are communicating with each other. CSE-1 to EEE-1: CSE-1 to LAN4 PC: Finally Attach this word file and your packet tracer file
