Hi,
I've got the following set under ppp:-
min-mtu=1280
mtu=1500
mru=1500
I can't see such a setting under L2TP.
When the L2TP tunnels establish, ifconfig l2tp00 etc. shows the mtu is 1420. The CPE connecting is set to 1500 and the path should allow 1500.
if I type ifconfig l2tp00 mtu 1500, this will force the mtu to 1500.
Why is the mtu only 1420?
Incorrect mtu set for L2TP interfaces
Re: Incorrect mtu set for L2TP interfaces
Hi tj-19, check docs
[l2tp] has 1420 as mtu by default
[l2tp] has 1420 as mtu by default
ppp-max-mtu=n
By default ppp-max-mtu=1420
Set the maximum MTU value that can be negotiated for PPP over L2TP sessions.
