According to the inheritance rule, the protocol ip command takes precedence over the
protocol ip inarp command in bundle-class. The protocol clns command is configured merely
for using it for integrated IP routing. The OSI routing packets go on the highest
precedence VC in the bundle while the OSI data packets, if any, use the lowest precedence
VC in the bundle. Other protocols, such as IPX or AppleTalk, always use the lowest
precedence VC in the bundle when they are configured. */
