[ovs-discuss] about L3 Route problem with two host

[feihu929 at sina.com]

I found the reason why the vm1 can not ping vm4.
It's may be I use vxlan to build the tun,  when replace geneve,  the vm1 can ping vm4

when use vxlan, run as below command in network1/2/3 host , 
[root at xxx ~]# ovs-vsctl set Open_vSwitch . external-ids:ovn-encap-type=vxlan 
the vm CAN NOT ping each other which not in the same logical switch and not in the same host node.

when use geneve, run as below command in network1/2/3 host , 
[root at xxx ~]# ovs-vsctl set Open_vSwitch . external-ids:ovn-encap-type=geneve
the vm CAN ping each other which not in the same logical switch and not in the same host node.

May be is a bug with vxlan?
