Ping works only one-way to host in VM virtualbox

Petteri_Oksanen — Wed, 15 Apr 2015 19:46:00 GMT

I am running EXOS VM's in Oracle VirtualBox.

I have a topology in this order: host1-sw1-sw2-host2.

I can ping from host2 to host1, but when I try to ping host1 to host2 the ping fails. I can't ping host2 from sw2 either. Here is snapshot of host1 and sw1:

Here is a snapshot of sw2 and host2:

Switch 1 and 2 are connected through OSPF.
What is the correct way to connect hosts in virtualized network?

I know there is no route to host from 192.168.11.3, but it still reaches 192.168.12.0/24 network, shouldn't it reach to the host also?

Thanks

- Petteri

Hi Petteri,
At first glance, I noticed in your config that ports 1 and 2 on each switch were deleted from VR VR-Default. They'll need to be added to a virtual router for all of the interfaces to work properly.
Try this:

code:

configure vr vr-default add ports 1-2

I may be missing something else, but I wanted to get a response out to you before my next meeting 🙂

Hi Drew

Thanks for the quick reply. All ports are assigned to virtual-router named "vrtesti", so disabling default VR was intentional. 🙂

I completely missed the add line just below it. I guess that's what I get for giving it a quick glance instead of studying 🙂
Maybe someone else will have a better idea.

If you can post your OSPF config (and any other relevant config pieces), I can get one of our lab interns to test it out.

Sure, here they are:

Switch1:
virtual-router vrtesti
configure ospf routerid 1.1.1.1
enable ospf
configure ospf add vlan switch1 area 0.0.0.0 link-type point-to-point

Switch2:
virtual-router vrtesticonfigure ospf routerid 2.2.2.2
enable ospf
configure ospf restart planned
configure ospf add vlan switch2 area 0.0.0.0 link-type point-to-point
configure ospf add vlan switch2host area 0.0.0.0 link-type point-to-point

And here is output from show ospf area 0.0.0.0 from sw2:

Hi Daniel

Awesome that you did all of this. So now you can ping from SW0 to SW3? I have exactly same settings, and it is a no-go. If I put them all under the same subnet, the ping works between hosts.

There may be problems with your VBox adapter settings.

Can you please run the following command on every VM? I'm particularly interested in the NIC X part of it...

vboxmanage showvminfo
Here's a sample output of the NIC part from my switch SW1. Your's should look similar.
NIC 1: MAC: 000130DF0902, Attachment: Host-only Interface 'vboxnet0', Cable connected: on, Trace: off (file: none), Type: Am79C973, Reported speed: 0 Mbps, Boot priority: 0, Promisc Policy: allow-all, Bandwidth group: none

If you're running VBox undes OS X, the command will execute right away. If you're running VBox under Windows you'll have to go to the VBox directory or add it to the path...

I have changed the network topology, but it is basically the same settings, and the problem is the same even in this setup. I tried with Windows-host and with Switch that acts as a host. I can ping from one host to another's default gateway, but can't reach the host.

RE: Ping works only one-way to host in VM virtualbox

dflouret — Thu, 16 Apr 2015 04:53:00 GMT

Why have you disabled NIC 2 in switch1host and switch2host?

By doing so adapter 3 now becomes port 1 in each one of those switches...

Can you post the VLAN and OSPF configs of all switches?

RE: Ping works only one-way to host in VM virtualbox

RE: Ping works only one-way to host in VM virtualbox

I'm recreating your lab, but I think the problem might be here...

Router1:

NIC 3: MAC: 080027F1B83E, Attachment: Internal Network 'link12', Cable connected: on, Trace: off (file: none), Type: Am79C973, Reported speed: 0 Mbps, Boot priority: 0, Promisc Policy: allow
-all, Bandwidth group: none

the central router is sharing the connection between switch1 and host1. the internal network adapter acts as a switch...

Yep, that's probably it.

When I disconnected the port everything worked OK. When I reconnected the port the pings from host1 started doing funny things.

Change the link name to link31 and you should be all set...

Oh right, that must've been from the testing that I did with LAG. I will test the ping now with right cabling.

Okay now I redid the cabling and this is the sad output on windows machines 😞

I could install wireshark on those windows machines and track what happens in there.

Ok, wireshark can see the incoming packet, but says no response is found. Pretty confused what is causing this.

Are those VMs also or are they physical PCs?
