I tested this with:
make sandbox SANDBOXFLAGS=--ovn
ovs-vsctl add-br br-eth0
ovs-vsctl add-br br-eth1
ovs-vsctl set open .
external-ids:ovn-bridge-mappings=physnet1:br-eth0,physnet2:br-eth1
ovs-vsctl show
The results:
Bridge "br-eth1"
Port "patch-br-eth1-to-br-int"
Interface "patch-br-eth1-to-br-int"
type: patch
options: {peer=br-int}
Port "br-eth1"
Interface "br-eth1"
type: internal
Bridge br-int
fail_mode: secure
Port br-int
Interface br-int
type: internal
Port "patch-br-int-to-br-eth0"
Interface "patch-br-int-to-br-eth0"
type: patch
options: {peer="br-eth0"}
Port "patch-br-int-to-br-eth1"
Interface "patch-br-int-to-br-eth1"
type: patch
options: {peer="br-eth1"}
Bridge "br-eth0"
Port "patch-br-eth0-to-br-int"
Interface "patch-br-eth0-to-br-int"
type: patch
options: {peer=br-int}
Port "br-eth0"
Interface "br-eth0"
type: internal
This looks close to correct to me. The "peer" names are all wrong,
though: the peer of a patch port is the name of another patch port, not
the name of another bridge.
I think that the code is intended to remove the patch ports when they
are not longer needed, but when I followed up with:
ovs-vsctl remove open . external-ids ovn-bridge-mappings
ovs-vsctl show
I still saw them.
Thanks,
Ben.
