Note:
A routing switch can also function as a router while running MPLS. The term "router"
in this document refers to a router in a generic sense or a Layer 3 Ethernet switch
running MPLS.
For the S9500 Series Routing Switches, only the line processor units (LPUs) and
VPLS service processor cards (SPCs) whose names contain such suffix like C, CA
or CB support MPLS. To enable the MPLS VPN function on an S9500 switch, you
need to configure an MPLS-capable LPU or VPLS SPC. You can identify a card
name suffix by the silkscreen at the upper right corner of the front panel of a card.
For example, the silkscreen of the LSB1P4G8CA0 card is P4G8CA and its suffix is
CA.
1.1 MPLS Overview
Multiprotocol label switching (MPLS), originating in Internet Protocol version 4 (IPv4),
was initially proposed to improve forwarding speed. Its core technology can be
extended to multiple network protocols, such as Internet Protocol version 6 (IPv6),
