I am having issues with mutual redistribution of EIGRP and OSPF. There are two points of redistribution. I have setup TAG to control the redistribution of routes. It doesn't seem to be working.
Here is the routing configuration. It is very similar on both routers except for the router specific parameters.
router eigrp 100
redistribute ospf 1 metric 10000 1000 255 1 1500 route-map ospf-to-eigrp
network 136.1.23.0 0.0.0.255
no auto-summary
eigrp router-id 150.1.2.2

router ospf 1
log-adjacency-changes
redistribute eigrp 100 metric 10 subnets route-map eigrp-to-ospf
network 136.1.245.0 0.0.0.255 area 0
network 150.1.2.0 0.0.0.255 area 0

route-map eigrp-to-ospf permit 10
set tag 77
!
route-map ospf-to-eigrp deny 10

route-map ospf-to-eigrp permit 20

When I redistribute EIGRP to OSPF, all the routes are being tagged with TAG 77.
When I redistribute OSPF to EIGRP I am trying to block all the routes with TAG 77 to be redistributed back into EIGRP.
EIGRP has some external router D EX which were originally redistributed into it from RIP. When these routes enter OSPF they show up is O E2 with TAG 77. My route map statement to block these routes from being redistributed back into EIGRP doesn't work. So even the reditribution router shows this as an OSPF E2 route learned from OSPF domain. It should block this route which is not happening.
Need help.
