Hi Babel WG, Donald suggested I make sure the WG members were comfortable with the language I've now included (to resolve IESG / IETF LC comments) in the info model draft, to express the fact it doesn't include parameters for operating Babel over IPv4. At the end of the abstract I added "This information model only includes parameters and parameter values useful for managing Babel over IPv6." At the end of the Introduction I added the paragraph: This information model only includes parameters and parameter values useful for managing Babel over IPv6. This model has no parameters or values specific to operating Babel over IPv4, even though [I-D.ietf-babel-rfc6126bis] does define a multicast group for sending and listening to multicast announcements on IPv4. There is less likelihood of breakage due to inconsistent configuration and increased implementation simplicity if Babel is operated always and only over IPv6. Running Babel over IPv6 requires IPv6 at the link layer and does not need advertised prefixes, router advertisements or DHCPv6 to be present in the network. Link-local IPv6 is widely supported among devices where Babel is expected to be used. Note that Babel over IPv6 can be used for configuration of both IPv4 and IPv6 routes. If this language is objectionable, please let me know. Thx, Barbara
