I guess, the third interface can be easily created during the setup, on the
lhost... this is what's required, right?
For example, by adding macvlan to the test interface:
ip link add ltp_mv0 link $(tst_iface) type macvlan mode bridge
Then, for the test route we can set either ltp_mv0 or $(tst_iface) interface.
