Configuring IRF member switches in IRF mode
Specifying an IRF domain ID for an IRF fabric
Introduction to IRF domains
IRF uses IRF domain IDs to uniquely identify IRF fabrics. IRF domain IDs prevent IRF fabrics from interfering
with one another.
See
, Switch A and Switch B form IRF fabric 1, and Switch C and Switch D form IRF fabric 2. The
IRF 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.
