Hi support
I enable OSPF between Nexus switch and Catalyst, the ospf is up, but the issue is that Nexus doesn't redistribute it's static routes configure to ospf instance.
the static routes in nexus are bellow.
192.168.10.0 255.255.255.0 11.0.0.2
192.168.11.0 255.255.255.0 11.0.0.2
192.168.12.0 255.255.255.0 11.0.0.2
i need Nexus switch to redistribute the three statics routes to Catalyst, Can someone help me with the configuration

Just wait a minute'
Static route config in nexus (I will assume it in global not other vrf)
If above correct why it not appear in rib of nexus?
How nexus advertise prefix not show in rib?

Bonjour !
Je suppose que vous utilisez ces commandes :
feature ospf
router ospf 1
redistribute static subnets
?
le 02-12-2023 01:02 PM
Bonjour Georg
merci de votre reponse, dans le Nexus, il n'y a pas la commande redistribute static subnets, ça demande d'utiliser la route-map
