Assigning a domain ID to an IRF virtual device
If LACP MAD detection is applied for multiple IRF virtual devices and LACP MAD detection links exist
among the IRF virtual devices, assign different domain IDs for the IRF virtual devices. If there is no
LACP MAD detection link among IRF virtual devices, or BFD MAD detection is applied, you do not need
to assign domain IDs to them.
Follow these steps to assign a domain ID to an IRF virtual device:
