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
