List Active PPP with ip address(where mtu 1480)

Hello all,
is there any method to print active ppp users with their ip ? but I would like to print only mtu 1480.
I tested belows but no chance

interface print where mtu=1480

No Ip listed

interface pppoe-server print where mtu=1480

no ip listed.

Thanks for all help

any idea ?

Something like this ?

:foreach i in=[/interface find actual-mtu=1480 running] do={/ip address print where interface=[/interface get value-name=name $i]}

Yes thats solves my problem… Really Thanks…
