Which Cisco router supports MPLS?

Which Cisco router supports MPLS?

P and PE Routers Cisco IOS® Software Release 12.2(6h) includes the MPLS VPN feature. Any Cisco router from the 7200 series or higher supports P functionality. The Cisco 2691, as well as any 3640 series or higher router supports PE functionality.

How do I enable MPLS on my Cisco router?

The six basic steps in the configuration are as follows:

1. Configure the loopback interface to be used as the LDP router ID.
2. Enable CEF.
3. Configure the label distribution protocol.
4. Configure the TDP/LDP router ID (optional).
5. Configure MPLS on core interfaces.
6. Configure IS-IS or OSPF as the MPLS VPN backbone IGP.

What is Cisco MPLS?

Cisco IOS Multiprotocol Label Switching (MPLS) enables Enterprises and Service Providers to build next-generation intelligent networks that deliver a wide variety of advanced, value-added services over a single infrastructure.

What is a MPLS router?

MPLS Defined Multiprotocol Label Switching (MPLS) is data forwarding technology that increases the speed and controls the flow of network traffic. With this method, each router on which a data packet lands must make its own decision, based on routing tables, about the packet’s next stop on the network.

Why is MPLS so expensive?

The high prices and consequently limited bandwidth available on enterprise WANs contributed mightily to the growth of the innovation of WAN Optimization by companies like Peribit Networks, Riverbed Technology and Silver Peak Systemsin the past decade: if bandwidth is expensive, then we need to wring every last bit (pun …

Do you need Cisco Express Forwarding for MPLS?

Configuration tasks for other MPLS applications are described in the feature module documentation for the application. MPLS switching on Cisco routers requires that Cisco Express Forwarding be enabled. Cisco Express Forwarding is enabled by default on a Cisco ASR 1000 Series Aggregation Services Router and cannot be disabled.

What does MPLS mean for Cisco ASR 903 router?

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.

What are the benefits of using MPLS in routers?

MPLS provides these beneficial applications: Additionally, it decreases the forwarding overhead on the core routers. MPLS technologies are applicable to any network layer protocol. What is a label?
