Re: [v6ops] [Idr] BGP Identifier

Hi Randy, and all,

Thanks for the discussion and sorry for the late. Assigning an id is not a
difficult issue, especially on a single router. But what number is to be
assigned might be an issue, especially in an ISP's large network, in order
to guarantee the uniqueness of the ids. In our network this kind of numeric
resources, e.g. IP addresses and cell phone numbers, is planned in advance
(usually with a careful designed numbering rule), and then delivered to
admins who located at different parts of the network. In the IPv4 world, we
take advantage of an IPv4 address, as it by nature an ideal id and fits into
the 32-bit length, and could be helpful in OAM. So perhaps we can use a
similar approach in an IPv6-only world, then the admins don't have to bother
to worry how to choose the ids. An id is not necessarily an IP address, but
IP address is a perfect candidate for an id.

Thanks and regards,
Peng
