Abstract
The control protocol used for constructing Point-to-Multipoint andMultipoint-to-Multipoint Label Switched Paths ("MP LSPs") contains afield that identifies the address of a "root node". Intermediatenodes are expected to be able to look up that address in theirrouting tables. However, thisis not possible if the route to the root node is a BGProute and the intermediate nodes are part of a BGP-free core. This documentspecifies procedures that enable anMP LSP to be constructed through a BGP-free core. In theseprocedures, the root node address is temporarily replaced by anaddress that is known to the intermediate nodes and is on the path tothe true root node. [STANDARDS-TRACK]
