Re: [Idr] Adoption call for BGP Auto-Configuration drafts (5/1 to 5/23/2022) - 3 weeks

[Natrajan Venkataraman <[e-mail]>]

Hello Susan,

Sorry for the late response as I was recovering from Covid.

I extend my support for the following drafts.

draft-acee-idr-lldp-peer-discovery:
- Operates at Layer 2 as an extension to the LLDP protocol.
- Security optional, provided by MACSEC.
- Does not provide (or require) a session layer.

draft-minto-idr-bgp-auto-discovery
- Operates at Layer 3 link-local multicast.
- Shared key authentication.
- Does not provide (or require) a session layer.

Thanks,
-Nats-

IDR Working Group,

BGP auto-configuration has four proposals for consideration for adoption by

the IDR Working Group:

- draft-acee-idr-lldp-peer-discovery

These proposals address the core issue of BGP auto-configuration in

different ways:

- What security model should we require?

- What OSI layer? (Layer 2, Layer 3)

- Does it provide a session layer?



A brief summary of these properties for each proposal under consideration

for adoption:

draft-acee-idr-lldp-peer-discovery:

- Operates at Layer 2 as an extension to the LLDP protocol.

- Security optional, provided by MACSEC.

- Does not provide (or require) a session layer.

draft-ietf-lsvr-l3dl + draft-ietf-lsvr-l3dl-ulpc:

- Operates at Layer 2.

- Security varies from optional to certificate based.

- Provides its own session layer as part of the protocol.

draft-minto-idr-bgp-auto-discovery

- Operates at Layer 3 link-local multicast.

- Shared key authentication.

- Does not provide (or require) a session layer.



draft-ymbk-idr-l3dn + draft-ymbk-idr-l3dn-ulpc

- Operates at Layer 3 with a link-local multicast component, and a unicast

 component.

- Security varies from optional to using certificate based with TLS.

- Uses TCP for session layer for its unicast component.



What protocol or protocols should be adopted by the Working Group for

BGP auto-configuration?
