In the MAP-E draft, I noted that:
- The Introduction says: "CE to CE traffic is direct, while BRs are traversed only for IPv4 packets that are destined to or are arriving from outside a given MAP-E domain."
- Section 5.2 on BR behavior has no provision for hairpinning CE-to-CE packets.
- Section 8.2 is titled "Hub & Spoke model", and says that some CEs may know subsets of Mapping rules, and then send some CE-to-CE packets to "a given BR".

Could you clarify the intent?
