[ipv6-wg] Clear Guidance for Enterprises

Thanks for your input Michael. The vagueness of the problem description reflects my own confusion.

We are not using IGP as of now, its a small NOC with a couple of devices.

This is not clear.

My question was that I have a /35 (say 2001:db8:2000::/35), and a router with three interfaces, one a p2p link with upstream, rest two interfaces are connected to two different segments as shown below:

                             │
                   ┌─────────┴───────┐
                   │                 │
                   │       Router    │
                   │                 │
                   └────┬───────┬────┘
                   A    │       │ B
              ┌─────────┘       └───────────┐
              │                             │
    ┌─────────┴───┐                 ┌───────┴──────┐
    │ C        D  │               E │             F│
┌───┴────┐ ┌──────┴──┐           ┌──┴─┐         ┌──┴─┐
│  dns1  │ │   mail1 │           │  S1│         │S2  │
└────────┘ └─────────┘           └────┘         └────┘

In the diagram above what will be the ip address at points A to F? C-F are servers and need static ip address.

Can you please elaborate this?

Thanks for your patience and time. I hope the questions I am having will be shared by many and will be addressed in the guidelines when published!
