The IESG has approved the following document: - 'Four-octet AS Specific BGP Extended Community ' <draft-ietf-l3vpn-as4octet-ext-community-03.txt> as a Proposed Standard This document is the product of the Layer 3 Virtual Private Networks Working Group. The IESG contact persons are Ross Callon and Adrian Farrel. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-l3vpn-as4octet-ext-community-03.txt Technical Summary This document defines a new type of a BGP extended community - four- octet AS specific extended community. This allows the BGP extended community to carry a 4 octet autonomous system numbers. Working Group Summary No controvery reported (see PROTO writeup by Danny McPherson in the I.D. Tracker). This was last called in both the L3VPN and IDR working groups. Document Quality The existing capability using 2 octet AS numbers is implemented and widely deployed. This is a very straightforward extension to support 4 octet AS numbers. Personnel Danny McPherson is the Document Shepherd for this document. Ross Callon is the Responsible Area Director. RFC Editor Note Please change the abstract to be: ABSTRACT This document defines a new type of a BGP extended community which carries a four-octet autonomous system (AS) number. Please update the last sentence of the Introduction as follows: OLD carry a four octets autonomous system number NEW carry a four octet autonomous system number Please replace section 5 (security considerations) with the following: 5. Security Considerations This document does not add new security issues. All the security considerations for BGP Extended Communities apply here. At the time that this document was written there were significant efforts underway to improve the security properties of BGP. For examples of documents that have been produced up to this time of publication, see [RFC4593] and [SIDR]. There is a potential serious issue if a malformed malformed optional transitive attribute is received. This issue and the steps to avoid it are discussed in [OPT_TRANS].
