In ppp.conf I am changed
 set mrru 1500 
on
 set mrru 1500 
 set mru 1504
on
 set mrru 1500 
 set mru 1500
on
 set mrru 1500 
 set mru 1504
 set mtu 1500
on
 set mrru 1500 
 set mru 1500
 set mtu 1500

and I have one result (see above)
only if I set:
 set mru 1500
i have 1 link with 64K and ifconfig show correct info:
