# Revision history [back]

i was providing the wrong mapped bridge. i have:

plugins/openvswitch/ovs_neutron_plugin.ini:bridge_mappings=physnet-external:br-ex


and was creating my external as

--provider:physical_network external


which should have been:

--provider:physical_network physnet-external


so darragh-oreilly you were right. this helped me understand as well: http://blog.oddbit.com/2014/05/28/multiple-external-networks-wit/

interesting, i don't have a vlan 4095 tag. googling this has been fascinating mickt! this is something that i can now avoid getting caught out on in the future.

thanks both of you for the help!!!!!!
