Changes from -00 version (based on comments) Justification for use of encap-SAFI (rather than new attribute) given Justification for use of single SAFI covering multiple encapsulations, rather than one SAFI per encapsulation given. Clarification of processing by a BGP speaker that does not understand some sub-TLV. New “opaque extended community” defined: can be used in cases where encap-SAFI is not really needed (i.e. no encapsulation parameters to signal). |
