Nexus 7k redistribute static into OSPF to block one static route

[Steev112]

Hi All,

i want to do redistribute static route into ospf on N7k, for example all want to advertise all static route except one route, i tried why access-list but unfortunately i can't block this route.

how can achieve it?

Thanks

Hi there,

Can  you provide the OSPF and relevant ACL config so we can see what needs tweaking?

cheers,

Seb.

Are you using a route-map?

!
!
ip access-list STATIC_ROUTES
  10 deny ip 1.1.1.0/24 any
  20 permit ip any any
!
!
route-map STATIC permit 10
 match ip address STATIC_ROUTES
!
!
router ospf 100
  redistribute static route-map STATIC
!

Hello

Try a prefix-list instead:

NX-OS

ip prefix-list tst deny 1.1.1.0/24
ip prefix-list tst permit 0.0.0.0/0 le 32
route-map stan permit 10
match ip address prefix-list tst

feature ospf
int x/x
ip address x.x.x.x y.y.y.y
ip router ospf x area x

router ospf 1
router-id x.x.x.x.
redistribute static route-map stan
end
clear ip ospf  redistribution
