Re: [nsp] multiplexing 2 ADSL (PPPoE - L2TP) connections for more bandwith

Sounds like the best solution would be MLPPP. You could do it with a
Unix box or a Cisco 1720 with 2 ADSL WIC's. Your LNS's
Virtual-Template will need to support ppp multilink and you may also
need to enable VPDN multihop depending on your config.
