PDU”), and insert the following new (fourth) paragraph: To avoid long-lived black holes, the procedure does not apply to a) the explicit withdrawal of unfeasible routes (that is, routes whose ROUTE-ID is listed in the Withdrawn Routes field of b) routes with a Security path attribute where under the applicable security policy a change in the security information an UPDATE PDU); contained in the path attribute implies a lowering of protection or otherwise results in a strong policy requirement no longer being met; or c) routes on which the Quality of Service has been reduced. Page 87 Annex B Add a new subclause B.3 as follows: B.3 Representation in BISPDUs Each of the 32-bit values A, B, C, and D computed as in B.2 shall be represented as a sequence of four octets in which the lowest octet number has the least significant value. The values A, B, C, and D shall appear in that order, with increasing octet numbers. NOTE -This octet ordering for each 32-bit value is the opposite of that specified in clause 6 for other PDU fields used to represent numbers as multiple octets. The difference preserves the octet order specified in RFC 1186. 2 COPYRIGHT International Organization for Standardization Licensed by Information Handling Services COPYRIGHT International Organization for Standardization Licensed by Information Handling Services 10747 94 W 4853903 0669607 202 I NTE R NATI O NAL ISO/IEC STANDARD 10747 First edition AMENDMENT 1 1994-1 0-01 1996-07-1 5 Information technology - Telecommunications and information exchange between systems - Protocol for exchange of inter-domain routeing information among intermediate systems to support forwarding of IS0 8473 PDUs AMENDMENT 1 : Implementation conformance statement proformas Technologies de l'information - Télécommunications et échange d'informa tion entre systèmes - Protocole pour échange d'information inter-domaine de routage parmi les systèmes intermédiaires supportant la transmission de PDUs de I'ISO 8473 AMENDEMENT 7 : Proformec de déclaration de conformité de mise en uvre Reference number ISO/IEC 10747:1994/Arnd.l:1996(E) COPYRIGHT International Organization for Standardization Licensed by Information Handling Services COPYRIGHT International Organization for Standardization Licensed by Information Handling Services - 30747 94 4851903 Obb9608 149 ISO/IEC 10747 : 1994/Amd. 1 : 1 9 9 6 ( E ) Foreword IS0 (the International Organization for Siandardkation) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. D r a International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75% of the national bodies casting a vote. Amendment 1 to International Standard ISOAEC 10747 : 1994 was prepared by Joint Technical Committee ISO/IEC JTC 1, information technology, Subcommittee SC 6, Telecommunications and information exchange between systems.
