Hi,
I have to admit at first that I don't fully understand the relationship between the MTU values of the physical and logical interface. Let's say this is my FTTH configuration:
- VLAN 40
- PPPoE MTU 1540 (PPP-Max-Payload Tag and LCP MRU show this value),
so I've setup my interfaces like this (on a CHR VM):
Can you explain me how and why does it work? It seems to my like PPPoE payload somehow doesn't count to the MTU physical interface? Shouldn't this PPPoE packets be dropped if they are larger than the MTU of their "master" physical interface ether1?
Thanks for any help!
