Clear adoption … either as INFO or maybe even BCP makes good sense. thanks --- tony _____________________________________________ “Simple, clear purpose and principles give rise to complex and intelligent behavior.

Section 4.3 explains the gradual degradation of BGP-PIC benefit as a result of the reduced platform support - For handling unlabeled traffic in case PE-CE failure, the last bullet in Section 4.2.2 indicates that an egress PE must always treat a core facing path as a backup path to avoid looping the packet in case of PE-CE link failure. The first statement in Section 5.1 indicates that the draft does not cover the failure of a CE node We would like to request adoption of the draft.

Name: draft-bashandy-rtgwg-bgp-pic Revision: 02 Title: Abstract Document date: 2015-11-09 Group: Individual Submission Pages: 26 URL: https://www.ietf.org/internet-drafts/draft-bashandy-rtgwg-bgp-pic-02.txt Status: https://datatracker.ietf.org/doc/draft-bashandy-rtgwg-bgp-pic/ Htmlized: https://tools.ietf.org/html/draft-bashandy-rtgwg-bgp-pic-02 Diff: https://www.ietf.org/rfcdiff?url2=draft-bashandy-rtgwg-bgp-pic-02 Abstract: In the network comprising thousands of iBGP peers exchanging millions of routes, many routes are reachable via more than one path. Given the large scaling targets, it is desirable to restore traffic after failure in a time period that does not depend on the number of BGP prefixes. In this document we proposed an architecture by which traffic can be re-routed to ECMP or pre-calculated backup paths in a timeframe that does not depend on the number of BGP prefixes. The objective is achieved through organizing the forwarding chains in a hierarchical manner and sharing forwarding elements among the maximum possible number of routes. The proposed technique achieves prefix independent convergence while ensuring incremental deployment, complete transparency and automation, and zero management and provisioning effort. It is noteworthy to mention that the benefits of BGP-PIC are hinged on the existence of more than one path whether as ECMP or primary-backup. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
