James,
summary-address command is used to summarise external routes into ospf not
otherwise, If you need 133.33.12.0/30 from eigrp to ospf to igrp, you will
have to summarise it when to a /24 address while distributing into ospf,
thus the summary-address 133.33.12.0 255.255.255.0 will apear under ospf
process on the router distributing eigrp to ospf, not on the router
redistributing ospf to igrp.
Let me know if you have ay further doubts
Sandro
