Overlapping interfaces permitted?

CriscoSystems

I'm doing some lab exercises that involve my flaky old 2521.

I think it might be even flakier than I thought, because I noticed that I configured both S0 and S1 interfaces with the exact same IP address, 192.168.2.1/24.

(Elsewhere in my lab is network 192.168.1.0/24 which is what I was going for on one of them.)

In any case, when I configured the second interface with that exact same address, shouldn't I have gotten an "Overlaps with Serialx" error message; rather than being allowed to proceed?

I've got 12.2(1d); the exact image name is c2500-jk8os-l.122-1d.bin

Anyone got insights?

Thanks.
