> 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.
