4108gl vlan routing

[Charles Gagliano]

I want to seperate my test environment from my production environment. But I want to still be able to connect to the test environment via Remote Desktop Connection. I will also need the test environment to communicate with my servers. What is the easiest way to accomplish this.

Is the 4108gl configured for routing
your current network already ?

If not, I'd start by reading this:

ftp://ftp.hp.com/pub/networking/software/59908853-1004-Adv-Trff-ch07-IProuting.pdf

Are you using public or private addresses
for your computers ? If public, and say if
you have a /24 block, you can
that into two /25 blocks, on for
test and one for production, and change the
mask and gateway on all your computers.

If you are using private addressing, you
can create a new network for one group
of your machines, and renumber them only.

If the 4108 is doing layer 2 only
right now, you can turn on routing

ip routing
ip route 0.0.0.0 0.0.0.0 a.b.c.d

where a.b.c.d is the default gateway,
probably same as specified as
ip default-gateway a.b.c.d

And then create a vlan for your
test machines, example:

vlan 500
name "test"
ip address 10.10.10.1 255.255.255.0
ip helper-address w.x.y.z
exit

where w.x.y.z is the dhcp server

and put your test machines on vlan 500

The router is brand new and just has the basic configuration on it. It has one default vlan and all ports are untagged.

The test environment is internal and will not be accessible to the public. Employees connect to the different test computers via Remote Desktop to test custom applications and that is it.

The internal network will use 192.168.0.0/24 and the Test network as 192.168.30.0/24.

I was re-reading your response. I have already turned on routing and added the route
0.0.0.0 0.0.0.0 a.b.c.d

How does one vlan know how to route to the other vlan if I do this.

Does the switch ad routes automatically for the different vlans that are setup

[Bruce Campbell_3]

As long as each vlan has an IP address, the
switch will route between them, if ip
routing is turned on.
