Usage
Information
Routers supporting 4-Byte ASNs advertise that function in the OPEN message. The 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.
For more information about using the 2– or 4-Byte format, refer to the
FTOS Configuration
Guide .
