Subject: Re: [Lsr] Working Group Adoption Poll for "OSPF Extension for 
PrefixOriginator" - draft-wang-lsr-ospf-prefix-originator-ext-01


Support, as this draft provide useful originial source router-id of prefix, as 
the same as RFC7794.

For topology deducing, it seems too hard to work according to current 
description in the document. For example, It is hard to represent mulptile 
links between two nodes if we only know two node-id information but lack of 
interface IP address or interface-id that is link attribute not be included in 
prefix flooding, thus there is no way to consider which link could be contained 
in which TE path, also, so many TE parameters of link need to be supplied for 
the deducing topology, TE metric, bandwidth, etc. Maybe there already have a 
complete solution but just not describe detailedly in document.



Thanks

This begins a two week adoption poll for the subject draft. Please send your

All authors have responded to the IPR poll and there is one

It is listed multiple times but references the same CN201810650141.
