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.
Ting

liao,

my read of your draft is that you're utilizing IGP extensions to flood
configuration informatioun through the network. have you considered
using netconf/YANG for doing so ? and if so what is wrong (what
are the shortcomings) of netconf/YANG to configure RAN routers ?
IOW why are exisiting configuration mencahnism not good enough ?

|    Abstract:
|      Segment Routing (SR) allows for a flexible definition of end-to-end
|      paths within IGP topologies by encoding paths as sequences of
|      topological sub-paths, called "segments".  These segments are
|      advertised by the link-state routing protocols (IS-IS and OSPF). 
And
|      a segment is identified by a Segment Routing ID(SID).  This 
document
|      proposes a method that the only selected SR nodes responsible for
|      allocating SIDs for a SR domain to reduce SID configuration 
required
|      on all SR nodes.
