I concur! If indexing by ifIndex is the "right thing" then the MIB
should do this directly, either by indexing by both ifIndex and IP
address, just ifIndex, or the OSPF method of having indexing by both
but using only one (which seems a pain if you're sharing an address
with another local interface).
