But if MAP uses the WAN prefix as its tunnel endpoint address, does BR need to keep all the records for CPEs (because the CPE's WAN prefix might be arbitary) ? Or do you mean the CPE's WAN prefix will be embedded with EA bits ? Would you please explain it a bit more ? > > 1) arbitrary IPv6 address (DS-lite) > Why it is arbitary ? Is it the source address of the tunnel endpoint ?
