Packet Tracer 4.0 Mod01 Challenge - VLSM addressing
Objective
Use Packet Tracer to complete the following skills

Implement a VLSM addressing scheme with RIPv2, static routing and default routing
Scenario
You have been given the address space 192.168.6.0/23 to subnet appropriately. "CorpNet" has the following
host requirements:
RTA LAN-150 hosts
RTB LAN-60 hosts
RTC LAN-30 hosts
Required Files
To complete this lab, you will need the following Packet Tracer Activity (.pka) files.

Act 1: VLSM Addressing

Open the “Mod01 Challenge - VLSM addressing.pka” file and follow the Instructions,
which are repeated here:
Step 1
Use VLSM to assign subnets starting with the largest host requirement first. Assign appropriate
subnets and IP addresses to all interfaces and the three PCs. The links between RTA and ISP and
the Web Server have already been configured. Configure the clock rate of 64000 on RTB’s
connection to RTA. Configure the clock rate of 64000 on RTC’s connections to RTA and RTB.

Step 2
Enable RIP v2 routing between RTA, RTB and RTC. Disable auto summarization and make sure that
only the serial interfaces between RTA, RTB and RTC are participating in the RIP process.

Step 3
On ISP a static route has been configured pointing to RTA for the 192.168.6.0/23 address space. On
RTA, set a default route pointing to ISP. On RTB and RTC, set a default route to RTA

*(Packet Tracer currently does not support the redistribution of default information).
Step 4
Verify connectivity by having each of the PCs ping the Web Server and the other two PCs.
