VLANS: VPT, Access and Trunk Ports

 

The first part of this lab required me to do a VLAN configuration for a campus network, with a Virtual Trunking Protocol, access and trunk ports, and inter-VLAN routing.

The first two steps for configuring a VLAN was to verify no VLANs are active and then to verify the default switchport status between SW1 and SW2.  

Next, I configured the links between switches as trunks. Here is the CLI prompts I used for SW2:


After that, I configured SW1 as a VPT Server in the VTP domain Flackbox.  

Then, command SW2 not to sync its VLAN database with SW1.
Next, command SW 3 to learn VLAN details from SW1.  
After that, I added Eng, Sales, and Native VLANs on all the switches, and then verified using the following commands:  
The next step was to configure the trunk links to use VLAN 199 as the native VLAN for security reasons.  
Finally, I configured the switch ports connected to the PCs with the correct VLAN configureation using the following commands:  
To verify the configuration was correct, I pinged to ensure ENG1 PC had connectivty to Eng 3, and that Sales1 had connectivity to Sales3.  It looked good!

ARP--Address Resolution Protocol

 ARP is a program that helps connect an IP address to a physical address (MAC) over a Local Area Network.   An analogy/pneumonic device.   Apartment's  Real  Person The IP address on a local address is like an apartment's address in a city. It's helpful to get packages delivered, but it doesn't tell the carrier which apartment it is going. ARP helps the packet get from the apartment gate to the apartment door.  Apartment's Real Person.

HSRP Configuration

Image
I began by configuring HSRP for the 10.10.10.0/24 using the IP addresses shown in the topology above. My first step was to check to see if G0/1 has been configured on R1 & R2.   It was not on either router, so I configured them and added a virtual IP address.    After that, I checked to see which was the active router (R2). Then, I checked to see that PC2 could ping the default gateway 10.10.10.1, followed by testing upstream connectivity.   I finished this portion of the lab by checking MAC addresses on the active router, the virtual interface, and PCs.

OSPF--Load Balancing

Image
The lab configuration entails three network hops from R1 to reach R4, passing through R2, while there are only two hops from R5. As all the interfaces are Fast Ethernet, there would be an excessive load on R5 which could cause issues.  To solve this problem, I configured the links between R1 to R5 and then R5 to R4 at the cost of 1500.   Two hops at 1500 = total cost of 3000. Three hops at 1000 (Previously set at auto-config) = 3000.  So now the traffic should be redistributed evenly. It worked!
