Given the network as in the diagram above, you need to create subnets with the given IP address of a major IP network. As for router configuration, you need to make the IP routing among all network segments. After finishing the configuration tasks, students have to ‘capture’ the configuration to text files and give to the examiner.

Note: Regarding the overall cooperation among team members –example: IP subnneting– the examiner watches the performance of the whole team and gives the score.

Section 1: IP Planning (20 points, for all team)

Use VLSM to assign IP address for each network.

Section 2: Basic configuration (20 points, for each student)

Overall requirements: all network segments in the network diagram can connect to each other.

a) Router name: Assign the names as given to each router accordingly.

b) IP address and subnest mask: Set IP address correcly for all related interfaces.

c) Password: Console, AUX, and vty lines are password protected, password= ‘cisco’; set the secret password to ‘class’.

d) Banner and descriptions: Banner contains the name of the student who configures it; descriptions of interface contain the name of the device it connects to. Banner (motd) example: Hello, this is router 1, configured by Alice. Interface description example: Connect to router ‘saigon’.

e) Backup configuration file: back up configuration file of each router using either TFTP or Capture Text.

Section 3: Routing (40 point, for each student)

Student 1:

Use EIGRP 100 for interface serial 1, 2, loopback 0. Use OSPF for interface serial 3.

Redistribute between OSPF and EIGRP (include the default-route which R1 learnt from EIGRP).

Student 2:

Use EIGRP 100 for interfaces serial 1, 2 and loopback 1

Configure the default-route through Lo0, and propagates it into EIGRP 100.

Student 3:

Use EIGRP 100 for interfaces serial 0/0, 0/1 and loopback 0

Configure static route (one command) for all remote routes through Lo0, and propagates into EIGRP 100.

Student 4:

Use OSPF for interfaces serial 0/1, fastEthernet 0/0 and loopback 0

Configure static route (one command) for all remote routes through Lo0, and propagates into OSPF area.

Student 5:

Use OSPF for interfaces serial 0, 1 and loopback 0

Configure static route (one command) for all remote routes through Lo0, and propagates into OSPF area.

Student 6:

Use OSPF for interfaces serial 0, Ethernet 0/0 and loopback 0

It matches the incoming packet to the access-list 201 permit any any statement and allows the packet into the router.
It reaches the end of ACL 101 without matching a condition and drops the packet because there is no access-list 101 permit any any statement.

It matches the incoming packet to the access-list 101 permit ip any 192.168.1.0 0.0.0.255 statement, ignores the remaining statements in ACL 101, and allows the packet into the router.

It matches the incoming packet to the access-list 201 deny icmp 192.168.1.0 0.0.0.255 any statement, continues comparing the packet to the remaining statements in ACL 201 to ensure that no subsequent statements allow FTP, and then drops the packet.

12. An established company has recently transitioned from outsourced LAN support to a completely in-house staff. The outsourcing company is no longer in business, so no records are available. There are many user complaints about application speed and availability. What two considerations apply to this situation? (Choose two.)

A network utilization baseline should quickly reveal application availability.

A period of 24 to 48 hours should provide a sufficient baseline to track normal network activity.

It is easier to start with monitoring all available data inputs on application servers, and then fine-tune to fewer variables along the way.

The initial baseline results have little relevance to current values after the network has been modified or grown in usage.

When it is practical, network administrators should attempt to automate the collection of performance data and stay away from manual collection.

Creating a network baseline data helps determine device thresholds for alerting.

40. An administrator is configuring a dual stack router with IPv6 and IPv4 using RIPng. The administrator receives an error message when trying to enter the IPv4 routes into RIPng. What is the cause of the problem?

RIPng is incompatible with dual-stack technology.

All interfaces have been configured with the incorrect IPv4 addresses.
