[rbak-nsp] New CLIPS sessions does not start

[Илья Савин]

Hi Mark,

Exactly! We have configured about 44000 subscriber vlans, but most of them
are not bound. Command "dot1q pvc 620:1500 through 3999" added 2500 vlans
in config:

 dot1q pvc 620 encapsulation 1qtunnel
  dot1q pvc 620:1500
  service clips dhcp context inet
  dot1q pvc 620:1501
  service clips dhcp context inet
  dot1q pvc 620:1502
....
  service clips dhcp context inet
  dot1q pvc 620:3999

 Now we changing this to

 dot1q pvc 620 encapsulation 1qtunnel
  dot1q pvc on-demand 620:1500 through 3999

It really helps. Thank you very much!

Regards, Ilya.
