[ipv6-wg] Clear Guidance for Enterprises

Hello all,

Resurrecting an old thread to share some experience when trying to start deploying ipv6 on a small London based ISP.

As a start we are deploying in  a test location which is setup as a "site". We have a /29 allocated and that's been divided into /32 for each site. Which is again divided into /35 for various functions in the NOC including for servers (DNS, Speed Test etc), subscriber allocation (/64 and a /56 per subscriber), loopback address etc.

There is sufficient guidelines and documentation to reach till this point. But from here on, it's pretty dark. Some of the question for which we have no clear guidelines are:

1. How will we assign address to routers? Like will we should be assigning 2001:db8:2000::1/35 or 2001:db8:2000::1/64 for router interface? 
2. How will we be assigning static address to (DNS?) servers? 
2.1 One IP from /35?
2.2 An IP from the /64 assigned to router interface?
2.3 An IP from a different /64 but from same /35?   

In the case of 2.3 will the routing work?

We have three interfaces in the router with one facing upstream and is using a /127 assigned by the up stream provider, of the other two one iface is for servers and another for BNGs. How are ipv6 address allocated in these interfaces. 

There are not much (atleast not to my google fu) resources addressing these nuts and bolts configuration information. 

I am writing this to share a from the trenches perspective to this discussion

Thanks
X.
