CLI Guide

When creating Confederations, all the routers in the Confederation must be 4- or 2-byte identied routers. You
cannot mix them.
Where the 2-Byte format is from 1 to 65535, the 4-Byte format is from 1 to 4294967295. Both formats are
accepted, and the advertisements reect the entered format.
For more information about using the 2- or 4-Byte format, refer to the Dell Networking OS Conguration Guide.
