NXOS ospf static default route change in behavior

[sherazmalik]

Currently on 7.0(3)I7(4) and looking to upgrade to 9.x. I see following statement in the upgrade guide:

"If you redistribute static routes, Cisco NX-OS requires the default-information originate command to successfully redistribute the default static route starting in 7.0(3)I7(6)."

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/93x/upgrade/guide/b-cisco-nexus-9000-nx-os-software-upgrade-downgrade-guide-93x/b-cisco-nexus-9000-nx-os-software-upgrade-downgrade-guide-93x_chapter_0111.html

Does anyone know what was the behaviour pre version 7.0(3)I7(6) and what is being changed ?

We have static default route redistributed via route-map by tagging it and don't use default-information originate. Will it affect default route advertisement post upgrade?

I think using redistrubte with route-map still work.

Under bug ID CSCwd35341, so you will be affected and you need to adjust your config i'm afraid.

Hello @sherazmalik 

You should do that :

ip prefix-list Redis_DEFAULT seq 5 permit 0.0.0.0/0
!
route-map DEFAULT_RM permit 10
match ip address prefix-list Redis_DEFAULT
!
router ospf 1
redistribute static route-map DEFAULT_RM
!
ip route 0.0.0.0 0.0.0.0 x.x.x.x
