The S7500E Series Ethernet Switches are distributed devices supporting Intelligent Resilient
Framework (IRF). Two S7500E series can be connected together to form a distributed IRF device.
If an S7500E series is not in any IRF, it operates as a distributed device; if the S7500E series is in
an IRF, it operates as a distributed IRF device. For introduction of IRF, see IRF Configuration
Guide.
MPLS Overview
Multiprotocol Label Switching (MPLS) is a new IP backbone technology. It introduces
connection-oriented label switching into connectionless IP networks, and seamlessly integrates the
flexibility of IP routing and the simpleness of Layer 2 switching.
MPLS is widely used on large-scale networks for it features the following advantages:

On an MPLS network, devices forward packets according to short- and fixed-length labels,
instead of doing Layer 3 header analysis and complicated routing table lookup independently.
This is a highly effective and fast data transmission method on backbone networks.
