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 byte or 2
byte identified 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 reflect the entered
format.
For more information about using the 2 byte or 4-byte format, refer to the Dell
Networking OS Configuration Guide.
