What we will now do is build a pseudo MPLS network between PE1 and PE2, establish an iBGP peering, create the associated customer VRF and then peer with the customer via OSPF Area 0. We require the following components to run MPLS over FlexVPN: IKEv2 and IPSec: to create security associations and encrypt our traffic. The Multiprotocol Label Switching Traffic Engineering (MPLS TE) technology integrates the MPLS technology with TE. A tunnel protection group provides end-to-end protection for MPLS TE traffic if a network fault occurs. MPLS over FlexVPN is a good choice if you want to extend your MPLS network securely over the Internet. MPLS is an integration of Layer 2 and Layer 3 technologies. It reserves resources by establishing label switched paths (LSPs) over a specified path in an attempt to prevent network congestion and balance network traffic. 3 CONTENTS; 11 Preface . Beginner. vrf . Example 4-17 shows a tunnel configuration in Cisco IOS with multiple path options. rd 10000:100. route-target both 10000:100. bgp next-hop loopback100. Following the topology used in all examples, here is both IOS XR and IOS configuration for a very limited IS-IS functionality. MPLS TE builds unidirectional tunnels from a source to the destination in the form of LSPs, which is then used for . Or you can use local xconnect between PW and dot1q-subinterface. Multi-Protocol Label Switching (MPLS) was created to improve packet performance in the core of the networks and is widely used for that purpose. CE1#conf t NHRP: to make direct spoke-to-spoke traffic possible. 07-20-2016 06:20 AM. . method 1. local xconnect in the PW-group. As such you can configure this feature on IOS-XR platforms such as ASR9000, NCS5500, and so on, as long as it runs IOS XR 7.5.1 or above. MPLS-TE learns the topology and resources available in a network and then maps traffic flows to particular paths based on resource requirements and network resources such as bandwidth. interface Tunnel1 description FROM-ROUTER-TO-DST1 ip unnumbered . And then stitching in this BDs xconnectx and dot1q subinterfaces. MPLS is an integration of Layer 2 and Layer 3 technologies. MPLS-TE learns the topology and resources available in a network and then maps traffic flows to particular paths based on resource requirements and network resources such as bandwidth. GNS3 router : 7200Image: 12.2In this video, I talk about MPLS traffic engineering configuration and also demonstrate FRR node and link protection with the he. MPLS is an integration of Layer 2 and Layer 3 technologies. These interfaces physically connect the ring topology and is the backbone running in Area 0. CE1 CE2 PE1 PE2 P1 IS-IS Configuration example for IOS and IOS XR. So, first up lets configure CE1 using an IP of 10.3.3.3/32 for the loopback and 10.1.13.3/24 for the link facing PE1. MPLS TE works by learning about the topology and resources available in a network. The video gets you started on Cisco MPLS Traffic Engineering (TE). Configure MPLS configuration in IOS-XR to implement Traffic Engineering (TE) The MPLS configuration should be done only on the MPLS tunnel head device and the RSVP commands for bandwidth allocation should be performed on all the IOS-XR devices. Basic topology with ASR9000 and IOS router for ISIS routing. The MPLS L3VPN we will configure will be a very basic one: On every PE, we will configure a vrf called cust-1. MPLS Traffic engineering is a set of tools that can improve performance in MPLS based networks. You need to configure all routers within the MPLS-TE path in your core with this configuration. where loopback 100 is used for MPLS TE traffic routing (per VRF MPLS TE). MPLS traffic engineering (MPLS-TE) relies on the MPLS backbone to replicate and expand upon the TE capabilities of Layer 2 ATM and Frame Relay networks. The Tunnels should not become a transit these physical interfaces as it blocks further MPLS path engineering. Below are the basic configurations. 0 Views.

By making traditional Layer 2 features available to Layer 3, MPLS enables traffic engineering. You enable the MPLS TE extensions using the mpls traffic-eng command under the router isis configuration mode. You must activate IGP. If you already have MPLS deployed in your network -- perhaps for a VPN . Licensing Requirements and Limitations for MPLS TE. Orhan ERGUN. Suva, Fiji. Through the directed LDP session a PE will learn the LDP label for the BGP next hop from the P router. By making traditional Layer 2 features available to Layer 3, MPLS enables traffic engineering. LDP allows routers to establish label-switched paths (LSPs) through a network by mapping network-layer routing information directly to data link layer-switched paths. Enable IS-IS on the interfaces, and set the link metric. It has also been adapted for other use cases, and one of the most important is traffic engineering. We will place 1 interface inside the VRF and we will configure a single static route towards the customer device. MPLS Traffic Engineering Tutorial APNIC 44 14 September 2017 Jessica Wei 2. .
