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 to 65535, the 4-byte format is 1 to 4294967295. Both formats are
accepted and the advertisements reflect the entered format.
For more information about using the 2- or 4-byte format, refer to the
FTOS Configuration Guide
