Redistribute iBGP to OSPF NXOS

I'm having a strange problem redistributing iBGP routes to OSPF on Nexus 9000.  Initially I had an open prefix list to get things working. Some of the routes weren't being redistributed to OSPF and I found this article which helped which said you need to 'match route-type internal'

 

https://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/nx-os-software/200185-Configure-Redistribution-of-iBGP-Routes.html

 

Now everything is working I am trying to lock down the prefix list but it seems to completely ignore the prefix list. Even if I only have a statement of deny 0.0.0.0/0 it still redistributes everything 

 

 

ip prefix-list permit-bgp-to-ospf seq 10 permit 10.0.10.0/24
ip prefix-list permit-bgp-to-ospf seq 10 permit 10.0.20.0/24

route-map redistribute-bgp-ospf permit 10
  match ip address permit-bgp-to-ospf
  match route-type internal
route-map redistribute-bgp-ospf permit 20
  match ip address permit-bgp-to-ospf

 

 

For the permit 10 statement my understanding is it's a logical AND statement (it needs to match the prefix list as well as be type internal) 

 

The reason I had the permit 20 statement is because some of the routes are not type 'internal' and I only want one prefix list to maintain.

 

I know the route-map is being referenced correctly because if I put a deny 5 statement then all the routes disappear. 

 

Anybody seen this before?

Thanks

high level below sequence same - so change it 10 and 20 so on

 

ip prefix-list permit-bgp-to-ospf seq 10 permit 10.0.10.0/24
ip prefix-list permit-bgp-to-ospf seq 10 permit 10.0.20.0/24

 

Do you have deny statemen for the prefix list ?

 

can you post complete configuration to understand better.

@MHM Cisco World  Thank you very much, good spot. That was the problem. I actually posted in here by mistake (was supposed to be the support forums) but I got my answer, thanks. 

 

@balaji.bandi  Thanks, it was just a typo on the post. It's correct on the router.
