Configuring IRF
General restrictions and configuration guidelines
To ensure a successful IRF setup, read the configuration restrictions and guidelines carefully before you
connect and set up an IRF fabric.
Software requirements
All IRF member devices must run the same system software image version.
MPU and IRF physical port restrictions
MPU restrictions
Make sure every IRF member has at least one MPU.
Physical port binding restrictions
• Use 10-GE or 40-GE ports for IRF connection.
• You can use the using tengige command to split a 40-GE interface into four 10-GE interfaces. The
following restrictions apply to these 10-GE interfaces:
{ You must use all of the four 10-GE interfaces as IRF physical ports or none of them as IRF
physical ports, but you can bind the four interfaces to different IRF ports.
{ Before binding the four interfaces to an IRF port, you must shut down all of the interfaces. If any
of the interfaces is in up state, the binding action will fail.
{ If you have bound one 10-GE interface to an IRF port, you must bind all the other 10-GE
interfaces to an IRF port before you can bring up any of them.
Port binding mode restrictions
• When you bind physical ports to an IRF port, set all the physical ports to operate in the same mode:
normal or enhanced. The physical ports of two neighboring IRF ports must operate in the same
mode.
• To use the EVB, TRILL, MPLS L2VPN, or VPLS function, you must specify the mode enhanced option
when performing IRF port binding.
Connecting IRF ports
When you connect two neighboring IRF members, connect the physical ports of IRF-port 1 on one
member to the physical ports of IRF-port 2 on the other.
