Mutual Redistribution w Route Maps

When doing mutual redistribution between OSPF and RIP or EIGRP on the
same router is it acceptable to use the following method using
route-maps to tag routes going from EIGRP to OSPF and vice versa, and
then to deny those routes from being redistributed back into the
originating protocol based on that tag setting. I find this method much
simpler than trying to identify specific routes for redistribution with
ACLs or taging the routes at the originating routers. Any comments on
this would be appreciated

router eigrp 100
redistribute ospf 10 metric 256 1000 255 1 1500 route-map ospf2eigrp
network 136.10.69.0 0.0.0.15
no auto-summary
!
router ospf 10
router-id 136.10.6.6
log-adjacency-changes
redistribute eigrp 100 subnets route-map eigrp2ospf
passive-interface Loopback0
network 136.10.6.6 0.0.0.0 area 0
network 136.10.100.0 0.0.0.31 area 0

route-map ospf2eigrp deny 10
match tag 900
!
route-map ospf2eigrp permit 20
set tag 500
!
route-map eigrp2ospf deny 10
match tag 500
!
route-map eigrp2ospf permit 20
set tag 900
!

Thanks....
5 days to go...
