Introduction [draft-fuxh-pce-boundary-explicit-control-framework-00] defines the framework for explicit control of region boundary in PCE-based inter- layer architecture. There is a requirements for PCEP extensions to support explicit control of region boundary. A new object could be introduced in PCEP message. 2. ERBO (Explicit Region Boundary Object) The format of ERBO object is the same as an ERO. The ERBO including the region boundaries information can be carried in PCEP message. 3. RSVP-TE Extension The PCEP message is extended as followings: ::= ::=[] ::= [] [] [] ::=[] ::= [] ::=[] [] [] [] ::=[] 4. Security Considerations TBD 5. IANA Considerations TBD 6. References 6.1.
