Ping works only one-way to host in VM virtualbox

[Petteri_Oksanen]

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

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
virtual-router VR-Default

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
virtual-router VR-Default

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

Area: 0.0.0.0 Type: Normal
Router Id: 2.2.2.2

IP addressing for hosts and configs can be seen from the snapshot.

Thanks!

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.

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 🙂
