Thanks Chuck. This is actually part of a greater redistribution plan to match routes already in EIGRP from another protocol and prevent them from going into IGRP. I then permit those routers in the other protocol into IGRP and deny the EIGRP routes in that protocol. Since I can use the tag to match the routes prior to going into IGRP, this scenario just got incredibly easy. Without the tags, my brain was starting to melt trying to figure out all the statements for the ACL.
