OSPF Prefix Suppresion for NX-OS

aweise
Level 1
Level 1

I'm configuring my network so it does not advertise all of my /30 subnets used for WAN tunnels. These IPs do not need to be routed and simply flood the OSPF LSA database.

 

This is easy to do on IOS and IOS-XE, but is there something in NX-OS that can do something similar to "ip ospf prefix-suppression" for a specific interface?

In IOS it was bit easy, try running some question marks under address family IPV4 on OSPF.

Please do not hesitate to click the STAR button if you are satisfied with my answer.

Under the interface config, I don't see anything that's similar:

 

NX(config-if)# ip ospf ?
authentication Authentication on the interface
authentication-key Configure the authentication key for the interface
cost Cost associated with interface
dead-interval Dead interval
hello-interval Hello interval
message-digest-key Message digest authentication password (key)
mtu-ignore Disable OSPF MTU mismatch detection
network Network type
passive-interface Suppress routing updates on the interface
priority Router priority
retransmit-interval Packet retransmission interval
shutdown Shutdown ospf on this interface
transmit-delay Packet transmission delay

 

I even looked under the "router ospf" config and there isn't much there, either.
