home networking tutorials

I will be setting up my CCNA lab in the next week or so using a setup nearly identical to the one in TechLabs.

I want to incorporate my Comcast cable modem into this setup. Does anyone have a favorite link to a tutorial on setting up such a home network that would allow both CCNA hardware practice and Internet surfing.

I've found a few things on the web that talk about using NetBEUI over TCP/IP, but I'm still somewhat confused over the configuration.

Thanks in advance for any input.

You bought 2 2501s and a 1924. Connect the 1924 to the cable modem on port 2. Connect a 2501 to port 1 and connect the other 2501 to port 9. Connect port 10 to your PC. Assign ports 1-2 to vlan 2. Assign 9, 10 and the catalyst to VLAN 3.

Connect serial 0 and 1 on the first router (DCE end of V.35 cable) to serial 0 and 1 on the second router.

On your switch if it starts at a menu:
k
enable
configure terminal
vlan 2
vlan 3
ip mgmt-vlan 3
ip address 192.168.0.2 255.255.255.0
ip default-gateway 192.168.0.1
interface e 0/1
vlan-membership static 2
interface e 0/2
vlan-membership static 2
interface e0/9
vlan-membership static 3
interface e0/10
vlan-membership static 3

On your 2501 connected to port 1.

configure terminal

interface ethernet 0
ip address dhcp
ip nat outside
ip access-group 100 in
no shut

interface multilink 1
ip address 10.0.0.1 255.255.255.252
ip summary-address eigrp 1 0.0.0.0 0.0.0.0 90
ip nat inside
no shut

interface serial 0
encapsulation ppp
clock rate 4000000
multilink-group 1
no shut

interface serial 1
encapsulation ppp
clock rate 4000000
multilink-group 1
no shut

ip nat inside source list 1 interface ethernet 0 overload

access-list 1 permit any
access-list 100 permit ip any any established

router eigrp 1
network 192.168.0.0
network 10.0.0.0 255.255.255.252
no auto-summary
passive-interface ethernet 0

On the other router do a little something like this:

configure terminal
service dhcp
ip dhcp exluded-address 192.168.0.1 192.168.0.5
ip dhcp pool mypool
network 192.168.0.0 255.255.255.0
dns-server <IP address of your ISP DNS server>
default-router 192.168.0.1

interface ethernet 0
ip address 192.168.0.1 255.255.255.0
no shut

interface multilink 1
ip address 10.0.0.2 255.255.255.252
no shut

interface serial 0
encapsulation ppp
multilink-group 1
no shut

interface serial 1
encapsulation ppp
multilink-group 1
no shut

router eigrp 1
network 192.168.0.0
network 10.0.0.0 255.255.255.252
no auto-summary
passive-interface ethernet 0

Thank you for the detailed reponse. Any other more general tutorials / articles on this subject? The results of my Google search on Windows home networking has been less than spectacular.

well windows networking all depends on what OS's you're running, whether you're running in a domain, or just a workgroup. Basically, if you're running a domain, it's easier to access network resources. But a workgroup is fairly simple too... just make sure all the machines have the same workgroup defined, and it helps if all the machines have the same account information so you don't have to enter it when you're connecting to a share. If you're running XP then the peer to peer thing gets to be a bit more of a pain in the behind as you HAVE to define at least one passworded account on each machine, but all in all, still not that much of an effort.

This is assuming, of course, all your machines are going to be on the same segment. If not, then it gets a bit more complicated
