Verifying link failure protection of the ring topology
# Disconnect all IRF links between two IRF member devices. (Details not shown.)
# Verify that the IRF fabric operates correctly in daisy-chain topology. (Details not shown.)
Verifying the BFD MAD configuration
# Disconnect two IRF connections: one between Device A and Device D, and the other between
Device B and Device C. The disconnect actions cause the IRF fabric to break down into two parts, as
shown in
