Support for IPv6 127-bit subnet mask on point-to-point networks

Hello Community,

Running MLXe boxes with 5.3.0b, I was wondering if /127 masks on p2p
interfaces were supported ?

According to RFC6164, it should be :
ftp://ftp.rfc-editor.org/in-notes/rfc6164.txt

I have found no mention of it in NetIron ConfGuide 5.3.0a. I will be
testing it anyway but wanted feedbacks for the community.

More Specifically, is the first address Prefixe::0000/127 usable ?

Thank you.

Best.

Y.

Hi Youssef,

If you look at the release notes of 5.3.00b and look into defect
DEFECT000391863 a /127 is unsupported on brocade. :(

Hello,

This is indeed bad news as I am starting IPv6 deployment on our new
backbone :-/

I am not sure a /126 would be a better solution regarding the potential
security threats it raises.

Maybe someone at Brocade is reading this thread and could give us a
feedback on this ? Greg ?!?

Thanks.

Y.
