> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the

> Components: KVM
> Affects Versions: 4.3.0

>
> When vxlan was merged, it included getBroadcastUriFromBridge, which gets the
> vlan tag from the physical interface attached to the bridge. It looks for
> (\D)(\d)(\D*)(\d*). If a vxlan bridge is found (brvx), it returns the second
> element of this match as the broadcast id (VNI) by calling a "toUri" method.
> Otherwise, it returns the fourth element, which would be the vlan id if the
> device were something like 'eth0.200'. In situations where the bridge is
> untagged (eth0), however, it would throw an exception in trying to turn an
> empty string into a broadcast URI, causing any subsequent router setup to be
> canceled.
> We need to restore the old behavior of returning empty if no vlan id exists.
