Irf Domain Id; Irf Split - HPE FlexNetwork HSR6800 Configuration Manual

IRF domain ID

One IRF fabric forms one IRF domain. IRF uses IRF domain IDs to uniquely identify IRF fabrics and
prevent IRF fabrics from interfering with one another.
As shown in
fabric 2. The fabrics have LACP MAD links between them. When a member device in one IRF fabric
receives an extended LACP packet for MAD, 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.

IRF split

IRF split occurs when an IRF fabric breaks up into two or more IRF fabrics because of IRF link
failures, as shown in
routing and forwarding problems on the network.
