The physical IRF ports of an IRF link must belong to the same MDC. Otherwise, the link cannot be
set up. See
Figure 25 The physical IRF ports of an IRF link must belong to the same MDC
IRF
Make sure at least one IRF link is up. Otherwise, an IRF fabric split occurs.
If you assign the physical IRF port of the default MDC to a non-default MDC, all IRF settings on the
port will be lost. To assign the physical IRF port of the default MDC to a non-default MDC, make sure
there are other IRF links in up state between the members. Otherwise, an IRF fabric split occurs.
For an MDC that uses the hardware resources of different IRF member devices, make sure there is
an IRF link in up state for the MDC between the member devices. Otherwise, the MDC cannot
forward data between the member devices. See
Figure 26 An MDC based on multiple members must have IRF links in up state between members
