Re: OSPF into IGRP posted 04/05/2000
This does *NOT* work.... summary-address is used for redistribution into
OSPF from other protocols.. The fact that it even kinda works (until you
reboot from what I've seen) is more of a bug then anything... In fact, I
just tried it on 12.0 and I doesn't even "kinda" work, but it did in 11.2.
Again, unless you have multiple classful networks to work with there is no
way to get this done without static routes.
