Good Morning List,
I was wondering if anyone out here (there :)) has a working config for an Alcatel 7750 to give out IPv6 to subscribers. We would like to allocate /112's as a link net between the CPE and the BNG. We then want to route a /64 or /48 over this link net.
Please don't hand out /64s. That prevents people subnetting their IPv6 in their home or office. You can always hand out /56 if you really think /48 is too much.
For our single subnet clients it will work, but it might be a case of taking the middle ground and handing out just /56's - I have seen/heard quite a few people handing out /56. I am on the same wave length at home - I have 3 subnets and as a result need bigger than /64 :)
All of this is configured in Radius.
The link-nets are configure using the "wan-host" option under the subscriber interface. The /64 or /48 subnets is part of a /36 configured as the "pd" option.
From what I was reading, it appears as if the link-nets needs to be /64...surely not ?
Not unless your vendor has a pointless restriction. The only RFC in the area is https://tools.ietf.org/html/rfc6164 which recommends /127 but there's nothing to prevent /112 from working if that's what you want.
The way I read the doc they only support /64 on the link-net - which seems *odd* :(
