There is a comment somewhere: IPCP will be ignored it LCP is not finished, obviously incliding PAP/CHAP
Those bytes are clearly within the IPCP configure request (as indicated by the length of 0x0016 = 22).I don't know what they mean and haven't found an RFC documenting them, but they are in the right format to be two more IP configuration options of types 0x81 and 0x83, with length = 6 and four zero bytes for the data.They might be something proprietary which someone put into the the PPP IPCP implementation by mistake (perhaps copied blindly from another implementation?). Possibly coincidentally, the option types have the same values as "IP Addresses" and "IP Address" from the IPCP standard, with the high order bit set.
