Hi, Hannes Thanks for your review and the good comments.
In this draft, SID can be automatically generated by a control node (the Segment Routing Management Nodes (SRMNs)）, and the SRMNs generate the SID mapping to each node in the SR domain， then the IGP extension flooding out to every node, each node will know the sid allocated to each other. While if we use Netconf/YANG, all the nodes in the SR domain should be supported the open interface to Netconf/YANG, which is not easy, for many ASGs, CSGs only support SNMP protocol in the IP RAN scenarios. So this solution could simpify the conguration of ASG,CSG(actually it is zero-configuratin for them), which is very important for the operation. Best Regards.

IOW why are exisiting configuration mencahnism not good enough ? /hannes On Wed, Oct 22, 2014 at 05:35:48PM +0800, [email protected] wrote: | In some situation where users expect to simply plug in a SR node and have | it automatically use Segment Routing. | This draft attempts to solve this need. | Expecting your review and comments.
