behavior of a 4-Byte router is slightly different depending on whether it is speaking
to a 2-Byte router or a 4-Byte router.
When creating Confederations, all the routers in the Confederation must be 4– or
2–byte identified routers. You cannot mix them.
Where the 2-Byte format is 1-65535, the 4-Byte format is 1-4294967295. Both
formats are accepted, and the advertisements will reflect the entered format.
