DallasRTR#
I'd like to filter a redistributed route from EIGRP into OSPF to all routers in AREA2 and AREA34. I have tagged the route 10.90.100.0/24 with tag 90 at the Tampa router where its redistributed into OSPF, on the Chicago router I used a distribute-list to deny the route tagged with 90. The route isn't present on the Chicago router, but Dallas and Arizona can still reach the redistributed EIGRP network. Ideally i'd like to deny it once on one of the upstream routers if possible.

I'd like to filter a redistributed route from EIGRP into OSPF to all routers in AREA2 and AREA34. I have tagged the route 10.90.100.0/24 with tag 90 at the Tampa router where its redistributed into OSPF, on the Chicago router I used a distribute-list to deny the route tagged with 90. The route isn't present on the Chicago router, but Dallas and Arizona can still reach the redistributed EIGRP network. Ideally i'd like to deny it once on one of the upstream routers if possible.
