The BSCI Study Guide explicitly says to use "distance eigrp" (with no
address or wildmask) for EIGRP, and the "distance" command within the
routing-protocol config (with an optional address/mask) for everything else.
I don't know if this is intended to imply that it doesn't / shouldn't work
or isn't supported for EIGRP...

ACK. Tweaking admin distance lives in the "Wrong, but sometimes Less Wrong
than anything else" toolbox for me. Tweaking admin distance per prefix...
*shudder*
