Recategorization of Extended Communities 0x8006-0x800a
draft-kothari-extcomm-codepoints-02.txt

Abstract

This document requests IANA to recategorize several entries in the Border Gateway Protocol (BGP) Extended Communities registry from "Experimental Use" to non-experimental.

1. Introduction

The Border Gateway Protocol (BGP) Extended Communities registry lists Extended Communities 0x8000-0x8fff as Experimental Use, in keeping with [RFC4360]. In practice, the use of Extended Communities 0x8006-0x8009, defined in [RFC5575] and 0x800a, defined in [RFC4761] is not Experimental. The most straightforward solution to this problem is to recategorize those code points as Standards Action.

2. Discussion

The other solution to this issue would be to update the relevant specifications to use code points from the currently defined Standards Action space. Given that there is deployment of the currently-allocated code points, there would be non-negligible development, testing and operational expense to migrate to new code points, without any significant benefit being derived. Given that there is no evident disadvantage to simply recategorizing the current code points, that solution is to be preferred.

Thanks to Andy Malis for his contribution.

4. IANA Considerations

This document requests IANA recategorize Extended Communities 0x8006-0x800a as Standards Action. It is noted that the relevant specifications are already Standards Track RFCs.

5. Security Considerations

No security considerations arise from this document.
