I appreciate the input, just trying to redistribute routes from OSPF 100 to OSPF 1 in a Nexus 5500, I configured a route-map accordingly but I'm still not seeing any of the routes in a downstream OSPF 1 router, below is the configuration, please let me know if I'm missing something here, thanks again!
ip prefix-list BRAZIL seq 5 permit 120.43.0.0/16 le 32
ip prefix-list BRAZIL seq 6 permit 29.184.0.0/16 le 32
ip prefix-list BRAZIL seq 7 permit 129.0.0.0/8 le 32
ip prefix-list BRAZIL seq 8 permit 18.134.161.0/24 le 32
route-map ospf100-to-ospf1 permit 10
match ip address prefix-list BRAZIL
router ospf 1
router-id 192.168.1.2
redistribute ospf 100 route-map ospf100-to-ospf1
passive-interface default

Try adding "subnets" at the end of redistribute command...

There is no option to add subnets at the end of the redistribute statement under router OSPF
redistribute ospf 100 route-map ospf100-to-ospf1 ?

Perhaps you could post the output of show ip ospf on the Nexus?
Also can you verify for us that the routes permitted in the prefix list are in the OSPF data base and learned in process 100?

Thanks for the additional information. But I am a bit puzzled. I see output that tells me about OSPF 1 but no output about OSPF 100.

Thanks for the additional information. It is helpful to see the information for OSPF 100. Could you post the output of the OSPF database entries for the LSAs for OSPF 100?

Hi Rich, will do in a few but from a configuration standpoint, is all supposed to be needed for OSPF redistribution in place? these are Nexus 5500 switches, thanks so much!

I looked in a config guide for N5500 and did not notice anything that indicates that you are missing any required part of the config. Since I do not know what version of NXOS you are running I can not be sure if the config guide I used matches the version you are running. And since we have not seen the complete config it is difficult to be sure if something is missing. I wonder if it would be helpful to configure a default metric for OSPF 1?
