@Dmitry What default delays do you suggest?

pado-delay=0,delay1:100,delay3:200,-1:500 ok?
Should that become an option which needs to be configured, or can it be setup statically?

By default we don't need delay, I think it must be configurable feature.

set service pppoe-server pado-delay delay 100 sessions 100
set service pppoe-server pado-delay delay 200 sessions 300
set service pppoe-server pado-delay delay 300 sessions 1000

and configuration for this
