[cisco-bba] terminating ADSL on Gig Eth 802.1Q

[xlr8]

Bonjour cisco-bba,

  We acctually terminate about 4000 ADSL PPPoE/PPPoA on PA-A6-OC3
  Cisco 7200.
  Prior to ADSL2+ we need to migrate from ATM to a 802.1Q VLAN on the
  Gig Eth port.(PPPoE only)
  It seems we can't aggregate more than 1200 PPPoE session?

  Our telco suggest us to consider Redback SE100, but I would rather
  keep our cisco 7200.

  Does anyone have a working configuration? What version of kboot/IOS
  are you using? Can I have a sample of a working configuration?

  our actual configuration :
  c7200-kboot-mz.124-5a.bin
  c7200-is-mz.123-5b.bin

  also tried with :
  c7200-is-mz.122-28.SB.bin
  c7200-kboot-mz.124-5a.bin

  about same result...
