RFC4638 on PPPoE?

[Joost Mulders]

Hi,

Does stock ppp (/usr/sbin/ppp) support RFC4638? (I.e, MTU > 1492 on PPPoE link).
If so, how to enable it?

I am running:

FreeBSD netx 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r317181: Thu Apr 20 05:39:11 UTC 2017     root@releng3.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64

ppp.log contains:

Sep  7 12:19:53 netx ppp[394]: tun0: Warning: deflink: Reducing configured MRU from 1500 to 1492

Thanks much!
Joost

Have you tried /net/mpd5 ?

You could track down these changes and see if they are now included in mpd5
