Configuring IPX MLS
The no ipx routing command purges all IPX MLS cache entries and disables IPX MLS.
The ipx security interface command disables IPX MLS on the interface.
In IPX, the two end points of communication negotiate the maximum transmission unit (MTU) to
be used. MTU size is limited by media type.
