[ovs-discuss] multiple GRE on OVS

[othmane]

Hi all,

 

I've established a gre tunnel between two virtual machines and it worked
fine, however, when I try to establish another one over the same link and
between two other VM, its doesn't work at all, the ping failed. My setting
is like this:

 

I have two host H1 and  H2: in H1, I have 2 VM: VM1 (192.168.10.5) attached
to bridge br1 192.168.10.7 and VM2 (172.16.30.5) attached to br2 172.16.30.7
and ovs (10.180.121.70). In H2 I have 2 VM: VM3 (192.168.10.6) attached to
bridge br1 192.168.10.8 and VM4 (172.16.30.6) attached to br2 172.16.30.9
and ovs (10.180.121.41). I have also br0 attached to the physical interface
on both H1 and H2. As I said when I set the second GRE tunnel between VM2
and VM4 ,the same way I set the first one, it doesn't work, I can't even
ping  between the two br2. The "route -n" is correct. 

 

Any help would be appreciated, thinks.
