Hey Brian,
thx for coming back.

> Are you sure the CPE will push over 100Mbps in mlppp?

Yep, it already does 200Mbps MLPPP, reaching at most a 50% cpu usage.

Now in the meantime we got a theory:
Single PPPoE session gets max-speed available, obviously ignoring the BW info
bound to our Virtual-Interfaces.
It _seems_ MLPPP somehow honors the BW info the Virtual-Interface presents:

sh int Vi2.304
Virtual-Access2.304 is up, line protocol is up
  Hardware is Virtual Access interface
  Description: PPPoE-transport
  Interface is unnumbered. Using address of Loopback0
  MTU 1492 bytes, BW 100000 Kbit/sec, DLY 100000 usec,

Now the only question that's bothering us:
How does one change this BW value for VIs?

Any hints greatly appreciated.

Regards, hk
