Specifying a domain ID for an IRF fabric

Introduction to IRF domains
IRF uses IRF domain IDs for uniquely identifying IRF fabrics. IRF domain IDs prevent IRF fabrics from
interfering with one another.
As shown in
2. The fabrics have LACP MAD detection links between them. When a member switch in one IRF fabric
receives an extended LACP packet for MAD detection, it looks at the domain ID in the packet to see
whether the packet is from the local IRF fabric or from a different IRF fabric. Then, the switch can handle
the packet correctly.
