Usage Information
Routers supporting 4-byte ASNs advertise that function in the OPEN message. The behavior of a 4-byte
router is slightly dierent 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 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 byte or 4-byte format, refer to the Dell Networking OS
Conguration Guide.
This command automatically restarts the BGP instance for the conguration to take eect.
