Cisco ACI /32 static route

[brian.holmes]

Our DNS team is asking us to add a static route for their Infoblox deployment

i.e

BD = 192.168.1.1/24

Appliance = 192.168.1.10

HA Loopback = 192.168.1.11

They cannot turn on Proxy ARP on their Infoblox appliance and are asking for the following static route:

192.168.1.11/32 next-hop 192.168.1.10

Should I just do this under the EPG or under the L3Out nodes?

Static routes are added on L3out on the leaf node profiles.

You can check current routing before adding it and after adding it on cli to confirm if there was a change made.

Hi @brian.holmes 

Since your HA Loopback IP is part of the BD subnet, you can't add it as a static route in a L3Out.

However, you can add it as a /32 route under the EPG and mark it as EP Reachability:

Stay safe,

Can you please explain to me the reason for having an HA loopback. What is the use of it?.
