Hi,
I'm setting up a layer 2 network over two virtual machines using
OpenvSwitch-2.5.2, like the picture shows below.
After reading the ovs official tutorials and some other articles, I've tried
the following cmds on each virtual machine:
# on vm1 ip link add dev veth0 type veth peer name veth1 ip link add dev veth3
type veth peer name veth4 ip netns add ns0 ip netns add ns1 ip link set veth0
netns ns0 ip link set veth3 netns ns1 ip link set veth1 up ip link set veth4 up
ip netns exec ns0 ip link set veth0 up ip netns exec ns1 ip link set veth3 up
ip netns exec ns0 ip addr add 10.0.0.1/24 dev veth0 ip netns exec ns1 ip addr
add 10.0.0.3/24 dev veth3 ovs-vsctl add-br br0 ovs-vsctl add-port br0 veth1
ovs-vsctl add-port br0 veth4 ovs-vsctl add-port br0 vx1 -- set Interface vx1
type=vxlan options:remote_ip=192.168.99.101 # on vm2 ip link add dev veth0 type
veth peer name veth1 ip netns add ns0 ip link set veth0 netns ns0 ip link set
veth1 up ip netns exec ns0 ip link set veth0 up ip netns exec ns0 ip addr add
10.0.0.2/24 dev veth0 ovs-vsctl add-br br0 ovs-vsctl add-port veth1 ovs-vsctl
add-port br0 vx1 -- set Interface vx1 type=vxlan
options:remote_ip=192.168.99.100
Turns out,
#vm1 ip netns exec ns0 ping 10.0.0.2 failed.
Even worse,
#vm1 ip netns exec ns0 ping 10.0.0.3 failed.
However, if I delete the vxlan port, on vm1, ping from veth0 to veth3 works
well as expected.
Am I missing anything so that this whole overlay network just won't behave?
