Bridge br-int is deleted on one switch and TEP corresponding to switch is also deleted from transport-zone.
Bridge br-int is created again.
TEP interface which was present on old br-int (that was deleted) is still present with UNKNOWN state in tep:show-state CLI and also in REST output of URL: http://localhost:8181/restconf/operational/ietf-interfaces:interfaces-state/
