Hi All, I have a question but can't find an answer from RFC 1661
During ppp negotiation, if A advertises MRU 1440, B advertises MRU 1460, do they have to re-negotiate to agree with a MRU? If so, should it be the lower MRU? If they don't need to re-negotiate, what MRU is actually being used? Is there any guideline for this? I observed a ppp nego debug between cisco 7200 and an adsl modem, the result appears to be if one end advertises 1500, it becomes the one regardless what MRU the other end advertises.
