3-0-carrying-intro.body

This specification contains two parts: definition of a new BGP NLRI

that describes links, nodes, and prefixes comprising IGP link-state

information and definition of a new BGP path attribute (BGP-LS

attribute) that carries link, node, and prefix properties and

attributes, such as the link and prefix metric or auxiliary Router-

IDs of nodes, etc.

It is desirable to keep the dependencies on the protocol source of

this attribute to a minimum and represent any content in an IGP-

neutral way, such that applications that want to learn about a link-

state topology do not need to know about any OSPF or IS-IS protocol

specifics.
