PowerPackage Segment Routing

This PowerPackage combines the content of the Segment Routing: MPLS and SDN – Concepts and Applications and SRv6 – Segment Routing with IPv6 – Concepts and Applications courses in one event. Compared to booking the courses individually, you save € 1.195,-.

Segment Routing (SR) will revolutionize routing in the MPLS backbone. By extending the routing protocols to include label distribution with global significance, the use of an additional protocol such as LDP can be dispensed with. However, this alone would not be a reason to replace LDP.

So SR also promises to eliminate the many disadvantages of classic MPLS traffic engineering (TE) with RSVP signalling and, in conjunction with SDN controllers, to make TE scalable, optimized and manageable. Furthermore, an SR network has the ability to guarantee fast rerouting (FRR) for all links in the backbone and can be seamlessly integrated into an existing MPLS backbone.

However, SR can also score points outside the MPLS backbone with its simple and scalable source routing concept with application options for service chaining or egress load sharing.

Segment routing has experienced a real success story in carrier backbones, but also in the infrastructures of larger corporate networks. While MPLS-based implementation of segment routing was predominantly used in the past, the advantages of SRv6, the variant for IPv6 infrastructures, are currently being increasingly recognized.

In fact, there is even a noticeable trend towards replacing MPLS with SRv6 in backbones. One piece of good news is that all of the performance features that can be used for MPLS and that we have come to love are also available with SRv6, such as scalable traffic engineering and fast rerouting, as well as the use of an SDN controller for automation.

SRv6 gains additional potential because it only requires a routed IPv6 network. This means that greater coverage can be achieved and the underlying IPv6 routing can be optimized.

Course Contents

Part 1

• Motivation and comparison with the classic MPLS solution
• SR architecture with MPLS data plane
• SR architecture with IPv6 data plane
• SR integration in IS-IS, OSPF and BGP
• Interaction of classic LDP with SR (migration phase)
• Effects on existing services such as L2 or L3 MPLS VPNs
• Topology Independent Fast Rerouting (TI FRR) with SR
• Comparison of classic MPLS-TE with RSVP to TE
• TE via an SDN controller
• The Path Computation Element (PCE)
• Extracting topology information with BGP-LS
• Setting up and monitoring TE paths with PCEP
• Application examples and use cases also outside the MPLS backbone

Practical exercises in a test network with Cisco IOS XR are used to illustrate the relationships. A suitable SDN controller is used to illustrate a PCE.

Part 2

• Motivation and comparison with the segment routing solution with MPLS
• SRv6 basic functions
• Implementation with the segment routing header
• Optimization through micro SIDs (uSIDs)
• Traffic engineering with SRv6 and SDN control
• Loop Free Alternate
• Interworking with MPLS-based segment routing
• Migration to SRv6
• Use of SRv6 in mobile networks

Practical exercises in a test network with Cisco IOS XR are used to illustrate the interrelationships. 

Target Group

The event is aimed at network planners and administrators who want to learn about the possibilities of SR and SRv6 and gain the necessary knowledge for integration or migration in their own network.

Knowledge Prerequisites

Good knowledge of IP, IPv6 and MPLS networks and especially routing with IS-IS or OSPF and BGP is required. Experience with LDP and RSVP in an MPLS backbone is advantageous.

Classroom training

Do you prefer the classic training method? A course in one of our Training Centers, with a competent trainer and the direct exchange between all course participants? Then you should book one of our classroom training dates!

Hybrid training

Hybrid training means that online participants can additionally attend a classroom course. The dynamics of a real seminar are maintained, and the online participants are able to benefit from that. Online participants of a hybrid course use a collaboration platform, such as WebEx Training Center or Saba Meeting. To do this, a PC with browser and Internet access is required, as well as a headset and ideally a Web cam. In the seminar room, we use specially developed and customized audio- and video-technologies. This makes sure that the communication between all persons involved works in a convenient and fault-free way.

Online training

You wish to attend a course in online mode? We offer you online course dates for this course topic. To attend these seminars, you need to have a PC with Internet access (minimum data rate 1Mbps), a headset when working via VoIP and optionally a camera. For further information and technical recommendations, please refer to.

Tailor-made courses

You need a special course for your team? In addition to our standard offer, we will also support you in creating your customized courses, which precisely meet your individual demands. We will be glad to consult you and create an individual offer for you.
