Are you sure? To me it looks like this feature also fixes PE=>CE,
because the primary egress PE also knows the backup egress PE, so if
it gets packet it cannot forward to 'LAN', it should be able to bypass
the packet to backup egress PE.
It's not obvious to me how the P can send it to backup egress PE, if P
cannot reach primary egress PE.
