They use different DLCIs for the LMI data. Cisco uses 1023 and ANSI uses 0.
Frame size and format is different.
What Cisco calls "Cisco LMI" is not Cisco propietary. It's known in the
industry as "Consortium LMI" and was the result of an agreed standard
between Cisco, Stratacom (bought later by Cisco), DEC, and Nortel. Old-
timers sometimes refer to it as "Gang of four" (now three). It's supported
on many platforms, including Cascade switches, etc.
