Configuring an IRF virtual device
Specifying a domain ID for an IRF virtual device
Introduction to IRF domain
To differentiate IRF virtual devices, each IRF virtual device is assigned a domain ID.
As shown in
Figure 7
, Switch A and Switch B form IRF virtual device 1, and Switch C and Switch D form
IRF virtual device 2. If there is a MAD detection link between the two IRF virtual devices, they send MAD
detection packets to each other through the detection link. The system statuses and operations of both IRF
virtual devices are affected. To solve this problem, specify different domain IDs for the two IRF virtual
devices.
After assigning a domain ID to an IRF virtual device, the extended LACPDUs sent by the member
switches carry the IRF domain information to distinguish the LACP detection packets from different IRF
virtual devices.
