Join Two internal networks 3

[Yardyy]

Hi, What would the easiest way be to join two internal networks together, basically, we have a 10.0.0.1, and a 192.168.77.1 network, and i would like everybody to communucate with each other. The main network is the 10.0.0.1, which has all the mail servers, DC, and fileserver, no servers are expected to be put in the 192.168.77.1. just workstations.



Many Thanks

Router. Or a server with 2 NICs, with a route from one nw to the other, and vice versa.

Hi, I would prefer a router, but, am finding it hard to find one, could you suggest one, or post a link for one.

I was looking at doing it through a server and adding the "add route" command, tried that and it never worked, do you know of any good resources for a step by step instructions on how to do it this way.

Many thanks

If your switch can do this, you could also set-up a VLAN for each.

Good luck,

I would recommend a layer 3 switch such as a Cisco 3560

What do you have now?

Hi, Thanks for the updates.
Currently we have a class c network, which is quickly running out of ipaddresses, the option was to switch to a class b internal network, but, I was not sure how to do that.

In terms of hardware we have have a couple of hp procurve switches, and several 3com superstacks. About 5 windows 2003 servers as well, and clients are all windows xp.

I am also pretty much limited in budget for this as well, i know cisco hardware can cost a lot, but its the best, and thats what you have to pay.

For VLans, do you need a special type of switch..?

Many Thanks

VLANs are intended to isolate network traffic, not combine it. Your Procurve switches will do VLANs.

If your budget is that tight, you could always setup some linux distro on an old PC and route with it.

I don't use Cisco at all. They're wildly overpriced.

Are both of these "networks" in the same physical location already? What connects the 2 networks now, is it the internet?

Cheers,

Let's say your class c that is running out is 192.168.5.0/24
Then in one HP ProCurve, make two VLANs (192.168.5.0/24 and 192.168.6.0/24), and do the same in the other HP Procurve. Doing this in both switches would provide redundancy. The ProCurve switches are layer three switches, so they will route between VLANs themselves. These would be considered your core switches. On each switchport in a certain VLAN can be plugged a 3COM, and into the 3COM the pc's in that VLAN. What is serving as the edge device to the internet?

Depends on the Procurve, Burt. I use 53xx, 41xx and 25xx Procurve switches and they will not route VLANs. Newer models may, but there's no guarantee.

What's the purpose of a layer 3 switch if it cannot route between its own VLANs???

Burt

 

[LawnBoy]

Those are layer 2 with "some" layer 3 features. Lots of switches are sold that way.

HP likes to be "creative" with their use of marketing terms in an attempt to lure business from other companies.

 

[burtsbees]

I see...what a sham!
L2 with L3 capabilities? Hell, a Catalyst 2950 could do that!

Burt

 

[LawnBoy]

There's nothing "creative" about the marketing, the L2 switches I have were advertised as such. The Procurve line does have L3 switches and even some L4 switches. Just because it says "Procurve" on the box doesn't mean it's a L3 switch.

I paid for layer 2 and got some layer 3 abilities for free. How is this a sham?

OMG, Cisco sells a layer 2 switch! What a scam!

[burtsbees]

Well, what layer 3 features do they have? To me, layer 3 = IP, and IP means layer 3 logical addressing, and in a switch that means vlans, and, well...they can't route between them? What's the purpose?
What am I missing here???

Burt

 

[brianinms]

Okay, maybe its not "creative" marketing its just different terminology. About the best thing HP has going for them is the lifetime replacement.

 

[LawnBoy]

Which switch? They must have 50 different products in the Procurve line, spanning from layer 2 to layer 4. Besides, VLANs are layer 2 (even according to Cisco). What terminology are you using?
