Set mtu on ppp0 device?

I want to lower the mtu setting of the ppp0 device. The pc connects with pppoe. Setting a different mtu on the eth[x] devices is easy enough, but the mtu on ppp0 persists at setting itself at 1492 no matter what I change in /etc/ppp/peers/dsl-provider or /etc/ppp/options.

pty "/usr/sbin/pppoe -I eth0 -T 80 -m 1452 -C [isp] -S [isp]"
mtu 1452

How do I override the mtu on ppp0?

(Debian, using the debian rp-pppoe package)

obviously i am too late

Obviously i am late. But it may help someone.

#ip link set ppp0 mtu 1452

add it to start up script somewhere
ppp0 - is ppp network interface inside linux kernel. where 1452 - mtu size actually.
To see if you have ppp0 interface do "ip link"
I assume that iproute is installed.
