# This test simulates trunk subports using vlan interfaces inside the VM.
|
||||
# It creates vlan interface for the subport and then adds it's MAC and ip.
|
||||
# After packet reaching the vlan interface, reply packet has to be properly
|
||||
# routed. This test adds this route like in this example,
|
||||
# If vlan interface inside VM1 has to reply to VM2, we add a route to VM2
|
||||
# via this vlan interface device
|
||||
#
|
||||
# sudo ip link add link eth0 name eth0.1 type vlan id 1
|
||||
# sudo ip link set dev eth0.1 address {mac}
|
||||
# sudo ip link set dev eth0.1 up
|
||||
# sudo ip a a {address}/24 dev eth0.1
|
||||
# sudo ip r a {vm2_address} via {gateway} dev eth0.1
|
||||
#
|
||||
# Note: Though we are creating vlan interface for each subport, ping test
|
||||
# will test only first vlan interface (i.e first subport)
|
||||
#
|
||||
# We can't use cirros image as it doesn't support vlans
|
||||
# smallest flavor for centos is m1.tiny-centos (RAM 192, disk 8, vcpu 1)
