Dear Authors,
Can you please let me know is there any  way to know the BGP speakers from the link state information.
As per information available from node descriptor, "BGP LS identifier" cannot be used to identify, since this is unique across all BGP speakers with in AS.

           | Sub-TLV Code Point | Description       |   Length |
           +--------------------+-------------------+----------+
           |        512         | Autonomous System |        4 |
           |        513         | BGP-LS Identifier |        4 |
           |        514         | OSPF Area-ID      |        4 |
           |        515         | IGP Router-ID     | Variable |
           +--------------------+-------------------+----------+
Is there any way to use Node descriptor or attribute information to know about BGP speakers among all nodes provided in LS information.
If this information is not provided in LS information, is it ok to add new filed or flag in Node attribute to identify BGP speaker.
