Not able to ping from VM application to VM

Hi All,

I have one UCS server in my lab, which has multiple VMs configured with IP range of 192.168.0.0/24 and each IP is pingable from each other.

Now All those VMs have some testing application installed on it which need multiple IPs. All those IPs are given in range of 10.0.0.0/24. Now I want both of these IP ranges to get pinged from each other.

Need your expert advice immediately to get it done.

Ashwani,

-You have a B or C series Server?

-What layer 3 device is going to do the L3 routing between those 2 networks?

Not able to ping from VM application to VM

Thanks Kenny for your response!!

It is B series server. Do i really need any L3 device? Isn't it possible to do it within this server itself. However if It is really required I have 7600 in my lab. I can use that.

Can we do it with VMDirectpath feature?

If it can be done with any of the above methods, that is fine with me.

Thanks in advance.

Hello Ashwani,

You don't need a L3 device to do this, neither a upstream swicth if all vnic created is converging to the same fabric interconnect.

The only thing that you have to pay attention is look each vNIC created is carrying the same vlan, they must be "native vlan" thick, to be delivery to the host without tagging.

Doing this you can create how many vnic you wanted and ping each other.

Ashwani,

Just to be sure we are on the same page... you need to make VMs within the IP range 192.168.0.0/24 to eventually be able to ping 10.0.0.0/24, right?  If that is the case you need a L3 device to do so.

Just curious, how were you thinking on using VMDirectpath for this intervlan routing?

VMDirectPath allows guest operating systems to directly access an I/O device, bypassing the virtualization layer, but I personally have never seen it doing that, might be unaware  

Hope this helps, if yes, rate it

I'm sorry, I got it wrong previously. To ping works between different range of networks you need a L3 device for sure, as Keny says.

please try the below steps. hope it will help.

you can ping ip from one virtual machine to another machine by using this step:
