Connecting three v machines via a router

susuMIT · ‎06-09-2009

Hello,

So far, I'm not sure what is my problem. I'm creating a virtual netwrok consisting from three machines with different subnets and a router. I'm using Quagga as a router running on Ubuntu.

After installing and configuring everything. I can't ping between the machines. It's like the router is not directing the packets among the machines. I run RIP routing protocol.

I did show interface and found that the interface is up and line protocol detection is disabled.

Can someone help me.

Do I need three routers to connect the three subnet.

I knew that it may becouse I need to connect the machines and the router via a cross-over table. How this can be done in VMWare.

Thanks is advance.

Welcome to the forums!

Give some more information, please:

1. "ifconfig -all" or "ipconfig /all" from all guests.

2. Is the router a guest, too?

3. What kind of Vmware network do you use? Bridged, NAT or host-only?

4. Routing table of your router.

If you found this information useful, please consider awarding points for "Correct" or "Helpful" replies. Thanks!!

2. The router is a guest and running Ubuntu

3. I created 3 LANs (I'm not sure if this is right.) and add three adaptes to the router guest machine to connect each adapter to one of the three guest machines.

4. I use Quagga and rip.

I posted here the routing table, rip table, and show interface

quagga-router# show ip route

Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF,

I - ISIS, B - BGP, > - selected route, * - FIB route

C>* 192.168.1.0/24 is directly connected, eth4

C>* 192.168.2.0/24 is directly connected, eth5

C>* 192.168.3.0/24 is directly connected, eth6

quagga-router#

quagga-router# show ip rip

That looks fine so far. Let's have a look at your virtual networks.

Which host OS do you use? Can you post screenshots of the Virtual Network Editor?

Otherwise describe which VMnet is used for bridging, NAT, "host-only" and your three networks. Describe which guest uses which VMnet.

If you found this information useful, please consider awarding points for "Correct" or "Helpful"

replies. Thanks!!

My host machine is Vista and here is a screenshot of my virtual editor..

AWo · ‎06-10-2009

Try this:

Delete the team, for now. Open the Virtual network Editor and assign different IP addresses to the virtual networks VMnet2,3 and 4.

Assign on of these networks to the vNIC of each guest and the router should be member of all three networks.

Configure the guests IP setup accordingly to these three networks.

Hello AWo,

I solved the problem by using wireshark.

I noticed that the interfaces order are different that what I applied in the team setting.

I swaped the interfaces and everything is working now..

Thanks a lot...
