The latter is wrong. The order of selection is:
1. Numerically highest IP addresss on a loopback interface, when
there are multiple loopback addresses.
2. IP address on the loopback address when only a single loopback is defined.
3. Numerically highest IP address on an active physical (or logical other than
loopback address)--active as in no shutdown
