HA1 link doesn't support /31-bit subnet mask for point-to-point links?

L3 Networker

Hi,

 

I'm setting up two PA5250s in HA and are connecting them up directly to each other.  Since these are point-to-point links, i tried using a /31-bit subnet mask, as that is our usual norm for point-to-point links as per RFC3201.

 

Does anyone know why you can't use a /31 for this when they're directly connected to each other?

 

Thanks,

Eugene

Is /31 IP supported on non HA interfaces?? I.E outside interface towards the internet.

It works. Just todat 20th-August-2022 i configured it on one of ther Interface on PA-3220.

Initially it was not working as there was two layer2 switches, inline. Even it was not working on tagged sub-interface.

I connected Router and Firewall directly. Manually set the firewall's port speed to 100mbps as Router port speed was 100mbps, not 1Gbps and it worked for me.
