Table 1: Feature Information for MPLS on Cisco Routers
Feature InformationReleasesFeature Name
Multiprotocol label switching
(MPLS) combines the performance
and capabilities of Layer 2 (data
link layer) switching with the
proven scalability of Layer 3
(network layer) routing. MPLS
enables service providers to meet
the challenges of explosive growth
in network utilization while
providing the opportunity to
differentiate services without
sacrificing the existing network
infrastructure.
In Cisco IOS XE Release 2.1, this
feature was introduced.
In Cisco IOS XE Release 3.5S,
support was added for the Cisco
ASR 903 Router.
