I think the following needs to be corrected in the softwire-map draft:
MAP Configuration
For a given MAP domain, the BR and CE MUST be configured with the
following MAP elements. The configured values for these elements are
identical for all CEs and BRs within a given MAP domain.
o The End-User IPv6 prefix (Part of the normal IPv6 provisioning).
o The Basic Mapping Rule and optionally the Forwarding Mapping
Rules, including the Rule IPv6 prefix, Rule IPv4 prefix, and
Length of EA bits
o The IPv6 address of the MAP BR.
o Hub and spoke mode or Mesh mode. (If all traffic should be sent
to the BR, or if direct CE to CE traffic should be supported).
The end-user IPv6 prefix is not identical for all CEs. On the contrary, it must
be unique per CE. For example uniqueness is reflected in EA bits in case of
shared IPv4 address.
