Section 12 says:

By restricting the 6rd domain to within a provider
network, a CE only needs to accept packets from a single or small set
of known 6rd BR IPv4 addresses.

It should say:

By restricting the 6rd domain to within a provider
network, a CE only needs to accept packets from a single or small set
of known 6rd BR IPv4 addresses and from other CEs within the 6rd domain.

Notes:

A CE also needs to accept packets from other CEs within the 6rd domain.
This happens when, within a 6rd domain, two customer sites want to communicate.
