1 Exercice de la certification Cisco : Packet Tracer Skills Integration Challenge Instructions Addressing Table

2 VLAN and Port Assignments Table Scenario In this activity, you will demonstrate and reinforce your ability to implement inter-vlan routing, including configuring IP addresses, VLANs, trunking and subinterfaces. Requirements

3 Assign IP addressing to R1 and S1 based on the Addressing Table. Create, name and assign VLANs on S1 based on the VLAN and Port Assignments Table. Ports should be in access mode. Configure S1 to trunk, allow only the VLANs in the VLAN and Port Assignments Table. Configure the default gateway on S1. All ports not assigned to a VLAN should be disabled. Configure inter-vlan routing on R1 based on the Addressing Table. Verify connectivity. R1, S1, and all PCs should be able to ping each other and the cisco.pka server. Commandes à effectuer pour S1 : en config t interface vlan 99 ip address (On ajoute une ip interface à S1 sur le VLAN99 xomme indiqué sur le tableau) no shutdown ip default-gateway (On ajoute une passerelle par défaut à S1 pour qu il puisse rediriger sur R1) (On va creer tous les VLAN indiqués dans le tableau et les renommer) vlan 10

9 Part 4: Verify DHCP and Connectivity Scenario : A dedicated DHCP server is scalable and relatively easy to manage, but can be costly to have one at every location in a network. However, a Cisco router can be configured to provide DHCP services without the need for a dedicated server. Cisco routers use the Cisco IOS feature set, Easy IP, as an optional, full-featured DHCP server. Easy IP leases configurations for 24 hours by default. As the network technician for your company, you are tasked with configuring a Cisco router as a DHCP server to provide dynamic allocation of addresses to clients on the network. You are also required to configure the edge router as a DHCP client so that it receives an IP address from the ISP network. Part 1: Configure a Router as a DHCP Server Step 1: Configure the excluded IPv4 addresses. Configure R2 to exclude the first 10 addresses from the R1 and R3 LANs. All other addresses should be available in the DHCP address pool. Step 2: Create a DHCP pool on R2 for the R1 LAN. 1. Create a DHCP pool named R1-LAN (case-sensitive). 2. Configure the DHCP pool to include the network address, the default gateway, and the IP address of the DNS server. Step 3:Create a DHCP pool on R2 for the R3 LAN. 1. Create a DHCP pool named R3-LAN (case-sensitive).

10 2. Configure the DHCP pool to include the network address, the default gateway, and the IP address of the DNS server. Part 2: Configure DHCP Relay Step 1: Configure R1 and R3 as a DHCP relay agent. Step 2: Set PC1 and PC2 to receive IP addressing information from DHCP. Part 3: Configure R2 as a DHCP Client 1. Configure the Gigabit Ethernet 0/1 interface on R2 to receive IP addressing from DHCP and activate the interface. Note : Use Packet Tracer s Fast Forward Time feature to speed up the process or wait until R2 forms an EIGRP adjacency with the ISP router. b.use the show ip interface brief command to verify that R2 received an IP address from DHCP. Part 4: Verify DHCP and Connectivity Step 1: Verify DHCP bindings. R2# show ip dhcp binding IP address Client-ID/ Lease expiration Type Hardware address AA Automatic

11 A Automatic Step 2: Verify configurations. Verify that PC1 and PC2 can now ping each other and all other devices. Configuration des PC : Avant toute manipulation il ne faut pas oublier de mettre les PC en DHCP et non en statique. Configuration de R2 : R2> en R2# conf t Enter configuration commands, one per line. End with CNTL/Z. R2(config)# ip dhcp excluded-address (On exclue les 10 premiers adresses des réseaux de R1 et R3 afin que les adresses comme ne soit pas distribuée car c est l adresse de passerelle) R2(config)# ip dhcp excluded-address R2(config)# ip dhcp pool R1-LAN (On crée une plage DHCP vide dans laquelle seront stockées les adresses) R2(dhcp-config)# network (On définit que les adresses distribuées par la plage seront dans le réseau )

12 R2(dhcp-config)# default-router (On donne l adresse de passerelle du routeur chargé du réseau afin qu elle puisse etre distribuée aux PC) R2(dhcp-config)# dns-server (On indique l adresse du serveur DNS afin qu elle puisse etre distribuée aux PC) R2(dhcp-config)# R2(config)# ip dhcp pool R3-LAN R2(dhcp-config)# network R2(dhcp-config)# default-router R2(dhcp-config)# dns-server R2(dhcp-config)# R2(config)# int g0/1 R2(config-if)# ip add dhcp (On indique que le DHCP distribura une adresse IP aussi à R2 afin qu il puisse se connecter à Internet) R2(config-if)# ex Configuration de R1 : R1> en R1# conf t Enter configuration commands, one per line. End with CNTL/Z.

13 R1(config)# int g0/0 R1(config-if)# ip helper-address (On indique à R1 que les adresses qu il reçoit sur le port 0/0 viennent du DHCP et sont destiné à etre distribuée, en effet les routeurs bloquent le DHCP par défaut, il faut faire un ip helper afin que les adresses puissent passer le routeur) R1(config-if)# Configuration de R3 : R3> en R3# conf t Enter configuration commands, one per line. End with CNTL/Z. R3(config)# int g0/0 R3(config-if)# ip helper-address Vérification de l adressage : R2#show ip dhcp binding (On vérifie les adresses qui ont été attribuée par R2) IP address Client-ID/ Lease expiration Type Hardware address AA Automatic
