Introduction 49 This memo proposes a LCAF type for BGP Extended Communities. 51 2. BGP Extended Communities Attribute 53 When a BGP Extended Community [RFC4360] is stored in the LISP Mapping 54 Database System for either policy or documentation reasons, it can be 55 encoded in a LISP Canonical Address as follows. 57 0 1 2 3 58 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 59 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 60 | AFI = 16387 | Rsvd1 | Flags | 61 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 62 | Type = XX | Rsvd2 | 8 | 63 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 64 | Type high | Type low(*) | | 65 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Value | 66 | | 67 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 69 Figure 1: BGP Extended Communities LCAF Type 71 3. IANA Considerations 73 This document instructs the IANA to assign a LISP LCAF Type value to 74 use as type for the proposed encoding [I-D.ietf-lisp-lcaf] (replacing 75 the XX value in Figure 1). 77 4.
