Analysis
You can use a ring or daisy-chain topology for a
three- or four-chassis IRF fabric.
For reliability, use the ring topology.
ID
IRF member IDs must be unique.
IRF members elect a master automatically. For a
member device to be elected the master, assign it
the highest member priority.
Make sure the IRFport bindings are consistent with
the physical connections.
For
high
availability,
interfaces to an IRF port. These ports will
automatically aggregate for load balancing and
redundancy.
