1. Introduction
This memo proposes a LCAF type for BGP Extended Communities.
2. BGP Extended Communities Attribute
When a BGP Extended Community [RFC4360] is stored in the LISP Mapping
Database System for either policy or documentation reasons, it can be
encoded in a LISP Canonical Address as follows.
0 1 2 3
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
