Tough nut to crack! Redistribution from EIGRP to OSPF and then IGRP again!

Hi there fellowship of the (token) ring!

I have a weird problem - the one who can crack this one is up for a virtual
round of beer on me...
(By virtual I mean...if we ever meet then I'll by you a beer)

Here is the setup:

EIGRP--->SENDING information about a summarized route of 1.1.1.1/21 via ip
summary-address eigrp 1.1.1.1 255.255.248.0 on the connecting interface!

OSPF receives this route via redistribution and sees it like 1.1.1.1/21 - So
far so good!

OSPF redistributes into IGRP, which cannot understand the /21 mask and
discards the route...

I can see an easy solution with some static routes and then redistribute
them into OSPF or IGRP, but is there an more elegant way of doing this, for
instance with something like a "summary-command" in ospf, or a range
command...

Any ideas greatly appreciated!

Nicolai
