Roman,
imagine this scenario: the ASBR is backbone router too..one of its serial
running OSPF with 28, the other one running IGRP with 24 mask.
So, when I want to redistribute OSPF to IGRP, (without using static route),
I can use summary-address..
I have tried this scenario and it's work,
but..is it legal?
or I have to use the other way: create loopback with prefix same with
serial that running OSPF and 24 mask (network type point-to-point
offcourse)
and redistribute this to IGRP
what do you think?

yes,
summary-address is for redistributing into OSPF
area range is for redistributing between areas (but those routes, can later
be redistributed into other protocols)
