You don't need to make full configuration because all routers have already been configured but they have some mistakes. Your task is to find these mistakes and fix them. Maybe the easy way is to remember full config, but better is to understand the right configuration. You need to add two networks for Lab 1 as we only have to add the networks we have on the router. For LAB 2 we add three networks, and for LAB 3 we add two networks. Wendell Odom. Cisco CCNA Exam #640-507 Certification Guide. (Cisco Press: 2000) pages 374-403.

The answers to numbers 1-3 are included:
1.Which statement describes the routing protocol OSPF (choose 3)
A.It supports VLSM
B.It is used to between Autonomous systems
C.It confines network instability to one area of network
D.It increases routing overhead over the network
E.It allows extensive control of the routing update
F.it is simpler to configure than RIPv2
ANSWER: A, B and C OSPF uses both AS numbers and areas to define routing table responsibilities. It includes the subnet mask in its frame allowing for Variable Length Subnet Masks. D is wrong because it only communicates its routing table to neighbors on initial Hello messages and multicasts to neighbors on changes (as opposed to RIP and IGRP which use update intervals and broadcast their entire tables). E is wrong because their isn?t must control since it doesn?t use holddown timers, etc. the way that RIP does. F is wrong because you have to map out both AS and areas whereas with RIPv2, you enter in Router Rip and the networks and that is it!! 2. Error detection schemes use which field of frame to detect error? A.MTU B.MAC C.FCS D.PDU E.ERR F. Flag ANSWER ? C. FCS (Frame Check Sequence) (This is used by Fragment Free switching mode on Cisco switches to detect errors without requiring the switch to wait for the entire packet before forwarding) 3. Which of the following are characteristics of microsegmentation? (Choose two) A. Dedicated paths between sending and receiving host are established B. the number of collision domains is decreased C. Broadcast domain are enlarged D. Multiple subnetwork broadcast addresses are created E. Multiple ARP tables are required on the connected hosts F. Bandwidth is dedicated to connect hosts ANSWER ? D and F (Microsegmentation is implementing a Layer 3 switch, so you basically just get the advantage of a multiport router)
