I have a Nexus 7K router, has 2 ospf process, ospf 1 and ospf2. OSPF1 has several subnets in 10.1.0.0/16 subnet range , OSPF2 has several subnets in  10.2.0.0/16 subnet range. I want to summary OSPF 1 subnets to 10.1.0.0/16 then redistribute to OSPF2.but OSPF 2 didn't receive 10.1.0.0/16. Below is the config


ip prefix-list all seq 10 permit 0.0.0.0/0 le 32

route-map all permit 10

  match ip address prefix-list all


router ospf 1

  router-id 10.10.3.9

  summary-address 10.20.0.0/16 not-advertise

router ospf 2

  router-id 10.10.3.1

  redistribute ospf 1 route-map all

This is an exact repeat of a post that you submitted in the WAN Routing forum. If you are going to repeat a post you could at least acknowledge that it is a repeat from another forum. I suggest that any discussion of this question be consolidated in the WAN forum.
