/31 netmasks are not supported and might not work. Are you sure?

Team,

My ISP has given me /31 network for a remote branch but on adding to RED15 i get the above error.

Any work around? that's without involving ISP to change the network.

Thanks

Hi Chacha Kairu

With XG I have taken test interface on which I am able to configure the /31 manually.

Can you please share the error detail or snapshot?

Am getting that error and the interface has refused to come up despite the link being up.

Thanks

It is kinda rare, that you get a /31 on a WAN Connection.

Which device does the dial into the ISP Network?

Am using wireless Radio from my ISP and they have no option for DHCP uplink.

Thanks

Ah, so you are using a 3G Stick for example on the RED? Or is there a router in front?

Not really, the connection is from radio to RED the only thing that is tagging on the radio side. Just want to confirm if /31 is workable on RED or if I should be worried about the warning.

Thanks
