Hi, Robert: We have stated our thoughts for your concerned issue in the introduction part(section-1 <https://tools.ietf.org/html/draft-ietf-idr-bgpls-inter-as-topology-ext-01#section-1> ) of this draft. The main reason is the consideration of deployment flexibility(Requiring every border router to run BGP-LS). Can it answer your concern? For your second question, using passive interface is another solution. If so, we can put the passive interfaces information within the newly defined inter-AS NLRI. Thanks for your comments, wish more comments from you. Best Regards.

As a side observation normally peering links are enabled in the IGP as passive - not "redistributed as static routes". Thx, R.

This draft is a work item of the Inter-Domain Routing WG of the IETF. Title : BGP-LS Extension for Inter-AS Topology Retrieval Authors : Aijun Wang Huaimo Chen Shaowen Ma Filename : draft-ietf-idr-bgpls-inter-as-topology-ext-01.txt Pages : 11 Date : 2019-03-06 Abstract: This document describes the process to build BGP-LS key parameters in multi-domain scenario, defines one new BGP-LS NLRI type(Inter-AS TE Link NLRI) and some new inter-AS TE related TLVs for BGP-LS to let SDN controller retrieve the network topology automatically under various environments. Such process and extension can enable the network operator to collect the connection information between different domains and then calculate the overall network topology automatically based on the information provided by BGP-LS protocol.
