Redistribution just does not work that way.
For example: you redistribute RIP into OSPF and OSPF into BGP
BGP wont have the RIP routes ! Why ?
Like Pat says: redistribution looks at the routing table.
If you say: redistribute RIP into OSPF, IOS looks at the routing table,
takes all RIP routes and puts them into
OSPF. Of course, the RIP routes stay in the routing table as RIP routes.
If you redistribute OSPF into BGP, IOS looks at the routing table, takes
OSPF routes and puts them into BGP.
Of course, you miss the RIP routes here......
If you are running 3 or more routing protocols on a router and you want
to redistribute everything to everything, the only way to do is is like:
router rip
redistribute bgp
redistribute ospf
redistribute eigrp
router ospf
redistribute bgp
redistribute rip
redistribute eigrp
router bgp
redistribute ospf
redistribute rip
redistribute eigrp
router eigrp
redistribute bgp
redistribute rip
redistribute ospf

Chris is right...not sure about your requirement, but, does "passive
loopback 0" under ISIS work for you?
