Redistribution and the use of Tags

I was hoping someone could help clarify my use of tagging during
redistribution.....

Lets say we are running 3 routing protocols: RIP, EIGRP and OSPF (OSPF
in the core). I want to do mutual redistribution. The steps I have taken
(which seem to work) are as follows:

* redistribute OSPF into RIP and set the tag on all routes to 77
* redistribute RIP into OSPF, but use a route-map to ONLY allow
routes into OSPF with tag=0

* redistribute OSPF into EIGRP and set the tag on all routes to 77
* redistribute EIGRP into OSPF, but use a route-map to ONLY allow
routes into OSPF with tag=0

Does this sound like the proper way to accomplish mutual-redistribution
without duplicating routes?

Thx.

Jim
