[Bgp-autoconf] Move forward with bgp autoconf requirements and design principle

["Dongjie (Jimmy)" <[e-mail]>]

Hi all,

It's been some time since our presentation on the IDR virtual interim. On that meeting we discussed the next steps, which include:

1. Confirm the minimal set of common requirements
2. Reach consensus on the design principles
3. Put the above two into a requirement document
4. Hand the solution discussion to the WG

Currently we are still at the first step, while hopefully we could finalized the minimal set of common requirements quickly (by end of this month?) based on the discussions we had before.

The minimal set of requirements we have are as below:

* Support IPv4 and IPv6 address family
* Support to use either interface or loopback address for BGP session
* Support to discover the peering IP address
* Support to discover the peering ASN
* Support authentication of control message
* Enable Layer 3 link liveness detection, such as BFD
* The capability of communicating arbitrary attributes to peers according to operators' need

Note the last one was under discussion before the virtual meeting, if you have any opinion on it, please share it on this list.

The second step may need more effort, which means more discussion on the mail list is encouraged, and we may arrange one or two conference calls if needed.

Once we get step 1 and 2 settled, step 3 should be relatively easier (hopefully:)).

Inputs are always welcome. Thanks.

Best regards,
Jie
