Command History

Version Description

9.9(0.0) Introduced on the FN IOM.

9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.

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.
