What MPLS basics?

MPLS is an acronym for Multiprotocol Label Switching which is a type of data-carrying technique for high-performance telecommunications networks. MPLS directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex look-ups in a routing table.

What are the components of MPLS?

The following MPLS components are configured on the PE switches but not on the provider switches:

  • MPLS Protocol and Label-Switched Paths.
  • IP Over MPLS for Customer Edge Interfaces.
  • BGP Layer 3 VPN Configuration.
  • Routing Instances for Layer 3 VPN.
  • Routing Instances for Layer 2 VPN and Layer 3 VPN.

What are the prerequisites to run MPLS?

MPLS is a forwarding method, in which packets are forwarded based upon labels. It is called as Multi protocol because it is going to support all the protocols like Ethernet, ATM, Frame Relay and PPP.

Which is the best example of MPLS setup?

While MPLS can seem complex, this example will show how to get a very basic MPLS setup up and running. In this example we will be focusing ONLY on making traffic between CE1 and CE2 routable and route it using MPLS.

How to configure a VPN with MPLS core?

If you are looking for an MPLS Tutorial or step by step mpls configuration examples, this basic MPLS VPN configuration example will guide you from configuring the first router to a 3 router MPLS core with 2 external sites.

What makes up the backbone of a MPLS network?

Refer to Cisco Technical Tips Conventions for more information on document conventions. An MPLS network is commonly a backbone network comprised of MPLS-enabled routers called Label Switch Routers (LSR). Generally, the network consists of a core LSR with an edge LSR that applies labels to packets.

How to configure a Cisco MPLS router step by step?

Step 1 – IP addressing of MPLS Core and OSPF. Step 2 – Configure LDP on all the interfaces in the MPLS Core. Step 3 – MPLS BGP Configuration between R1 and R3. Step 4 – Add two more routers, create VRFs. We are now going to start using VRF’s.
