You can use route-maps to control which routes the routing protocols are sending.

Here is an ospf example: EIGRP would be similar.

access-list 10 permit

route-map ospf-filter deny 10

match address 10

route-map ospf-filter permit 20

router ospf 1



network area 0

network area 1

distribute-list route-map ospf-filter out

Hope this helps.
