Figure 16-12: MultiProtocol Label Switching (MPLS) module
The MultiProtocol Label Switching (MPLS) module contains a powerful set of network
processors that are specifically programmed to implement the MPLS function. The
module has no external ports, but contains four full-duplex Gigabit Ethernet internal
ports that connect to the BlackDiamond backplane switch fabric. Each internal processor
provides media-speed packet processing for two internal full-duplex Gigabit Ethernet
ports. The MPLS module operates in a one-armed fashion:
• Receiving frames from the switch fabric.
• Processing the frames.
• Transmitting the frames back into the switch fabric which then sends them to the
appropriate I/O module.
Software Requirements
The MPLS module requires that you load ExtremeWare version 6.1.8 build 12 or later on
the MSM64i module and on the MPLS module, BootROM 7.0 or later on the MSM64i
