9-1 Build-a-Network: Challenge 1

For this Activity you will be configuring a network in Packet Tracer.

Foster 202 Co. has a main office in Burlington and a smaller office in Montreal. They are connected by a T1 Serial link.

Networks:

172.16.0.0/30 BTV-MTL Link
172.16.10.0/24  BTV Core
172.16.5.0/24  BTV Users
172.16.6.0/24 BTV Data Ctr
172.16.20.0/24 MTL Net

Gateways:

172.16.0.1 BTV-Router
172.16.10.1 BTV-Router
172.16.5.1  BTV-Dist-SW
172.16.6.1 BTV-Dist-SW
172.16.20.1 MTL-Router

Lab 1 Goals:

Only configure Foster 202 Co. Network - ISP's and Remote Sites are the next lab (Challenge 2)

Configure Interfaces

Configure BTV Multi-Layer Switch VLANs

Set up OSPF Routing

Ping successfully among BTV-User, BTV-DC, and MTL networks

Changing the router names

Command:

Hostname (name)

Recommended Steps and Hints

Configuring Interfaces

Montreal is the simpler site, so start there

The Montreal Switch is layer 2 only and needs no config

Configure connected interfaces and make sure they can ping each other - don't worry about routing yet

REMINDER: Change port status to on!!

The BTV-DIST-MultiLayer Switch is the only device using VLANs!

• Remember - on multi-layer switches, the IP is assigned to the VLAN not the interface
• Ports need to be assigned to the correct vlan

make sure you are able to ping adjacent interfaces before moving on

For Multi-Layer switch, have to enable routing:

(config)#ip routing

For Vlans 5 and 6 and 10:

(config)#vlan ##

(config-vlan)#name (name)

(config)#interface vlan ##

(config-if)# no shutdown

(config-if)#ip address (Address) (MAC/Mask)

Configure trunk ports to the edge switches:

• Before setting switchport trunk mode, you need to configure the “encapsulation”
• On each trunk port, “switchport trunk encapsulation dot1q”
• This defines how the packets are “tagged”

Router>enable

#config terminal

(config-if)#int fa0/(num)

(config-subif)#switchport access vlan (num)

Then switchport mode trunk

Save Configuration:

copy run start

Make sure you are able to ping adjacent interfaces before moving on:

Configuring Routing

We are using OSPF to build routing tables - no static routes are needed

Remember - routing configuration is a multi-step process

• Turn on routing (multi-layer switches only)
• Create ospf instance
• Configure instance to advertise all directly connected networks
• OSPF config uses wildcard notation for subnet masks

Create an OSPF instance: The process ID specific to that router

#(config) router ospf instance_number (usually just 1)

Add all of the Directly Connected Networks on that router

#(config-router) network (IP Address) (Inverse Mask=the last has to be the remainder of 255) area 0

MTL Router:

All laptops should be able to ping each other:
