Thanks, I didn't mention but current ppp options are:

# cat /etc/ppp/options
debug
logfile /tmp/ppp
noipdefault
defaultroute
noaccomp
nopcomp
nocrtscts
lock
maxfail 0
lcp-echo-failure 15
lcp-echo-interval 30
lcp-restart 25
pap-restart 25

and pppd starts with:
/usr/sbin/pppd nodetach ipparam ppp0 ifname pppoe-ppp0 nodefaultroute
usepeerdns persist maxfail 1 ip-up-script /lib/netifd/ppp-up
ipv6-up-script /lib/netifd/ppp-up ip-down-script /lib/netifd/ppp-dow
