Topology
You can use a ring or daisy-chain topology for a
three- or four-chassis IRF fabric.
For reliability, use the ring topology.
Ring topology (see
Member ID
assignment
IRF member IDs must be unique.
Device A
—1.
Device B
—2.
Device C
—3.
Device D
—4.
Master device
IRF members elect a master automatically. For a
member device to be elected the master, assign it
the highest member priority.
Device A.
IRF port bindings
Make sure the IRFport bindings are consistent with
the physical connections.
For high availability, bind multiple physical
interfaces to an IRF port. These ports will
automatically aggregate for load balancing and
redundancy.
