Help setting up a home lab using Cisco kit and a Virgin Superhub

[CCNA_Student8]

Hi everyone,
 

I've just started my CCENT course and so I'm trying to create a lab that is segregated from my home LAN, initially using a Virgin Superhub and a Cisco 1841 router.  Please bear in mind that I'm a beginner at this, so it may not make sense or be completely illogical...

The superhub for those that don't know, is a rebranded, restricted netgear VMDG480.  It's essentially a cable modem and wireless router combined.

The normal everyday LAN side of the network was setup by default to receive an IP via DHCP from the superhub in the 192.168.0.1 /24 range.

Initially, I thought I could tidy things in preparation for my lab setup, by configuring the LAN subnet mask on the superhub to /16 and using 192.168.0.0 range for my 'everyday' network and 192.168.1.0 range for my 'home lab'. (Good idea or bad?...)

Unfortunately, I'm unable to do that as the superhub only allows the last octet in the mask to be changed, so I changed the mask and it now reads 255.255.255.128, with the idea that I can still have 2 separate networks.

From the picture above you can see the devices on the right hand side are all connected directly to the superhub and continue to work as normal.

On the left side is where I've introduced a Cisco 1841 router and a laptop to test.

The details of each device are;

Virgin superhub
LAN:192.168.0.1
DHCP scope: 192.168.0.2 - 192.168.0.126


Cisco 1841
Fast Ethernet 0/1: 192.168.0.126
255.255.255.128

Fast Ethernet 0/0: 192.168.0.129
255.255.255.128
 

PC2 (wired laptop connected to FE 0/0)
IP: 192.168.0.200
255.255.255.128
Default Gateway: 192.168.0.126 (Cisco 1841's IP address)

Would someone be so kind as to review this and tell me where I'm going wrong please?

I thought about ripping out the superhub completely but I'm tied to it by my ISP :(

Also, could you tell me why int fa0/1.2 sub interface needs to be created? Can't it just be fa0/1 ?

Hi Pete 

I know this is an old thread, however, I found it on a google search as I'm trying to do the exact thing as the OP.

I have followed your procedure up to the highlighted stages below, but I'm a tad confused at this point.

From how I read it, Int fa0/0 is on the router, however, the switch trunk/switch mode commands are for the switch.

If possible Pete, could you provide the seperate commands for the switch and router and I'll have another bash at it.

Any help and feedback very much appreciated.

Cheers.

Connect your 3560 to the second port on the router and configure a trunk port on the switch and add vlan 2:

int fa0/0 (connected to 1841 router)
switch trunk encapsulation dot1q
switch mode trunk

vlan 2
name Home_Lab

Connect your PC to the second switchport and add vlan2:

int fa0/1
switch mode access
switch access vlan 2
no shut
