On ASBR ( EIGRP-OSPF) summarization is configured
in ospf process
summery-address 10.1.0.0 255.255.0.0
redistribute eigrp 11 subnets
in eigrp process
redistribute ospf 10 metric 2000 0 255 1 1500
With this 10.1.0.0 /16 subnet is redistributed in OSPF domain but it got reflected back to EIGRP domain from the same router !!
Routers in EIGRP has now
10.1.0.0 /16 route in routing table. This is the only ASBR between EIGRP and OSPF.
Please share the experience. We may need to filter the summerized route going back to EIGRP with prefix-list and route-map.
