If want you meant by using only one ACL for both task is, "You are only
allowed to invoke that ACL once to accomplish both task" then the solution
that Luca provided will still apply, however since the ACL applied to RIP
have filtered out all RIP routes except your desired route, it might not be
necessary to even use distribute-list in EIGRP, just redistribute rip into
EIGRP <do not forget the metric values>.
