One IRF fabric forms one IRF domain. IRF domain IDs prevent IRF fabrics from interfering with one
another.
In Figure 10, D
evice A and Device B form IRF fabric 1, and Device C and Device D form IRF fabric 2.
These fabrics have LACP MAD links between them. When a member device in one IRF fabric receives an
LACP MAD packet, 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 device can handle the packet correctly.
