MPLS Procedure

5.76

MPLS Introduction

Changing Switch Mode  By default the NPT is configured as PB (Provider Bridge) with only L2 capabilities  For MPLS capabilities, change the switch mode to PE (Provider Edge)  Both NPT, BG and XDM MPLS cards require a license for card activation as a PE  Each PE must have a unique identifier, therefore we need to also set the PE_ID of each data card 6.76

MPLS Introduction

Switch Configuration – NPT 2

1. Click the Switch 2. Go to “Configuration” 3. Set the switching mode to: “MPLS-PE”* 4. Configure a unique PE_ID

Creating Tunnels

Global Services Division ECI Training Department 14.76

MPLS Introduction

Objectives  Creating a P2P Tunnel  Creating a P2MP Tunnel

15.76

MPLS Introduction

Creating Tunnels

Create Tunnel Window

16.76

MPLS Introduction

Basic Tunnel Parameters     

Tunnel Name Customer LSP Type CoS BW (Mb/s)

Tunnels are defined by CoS and BW – only services with the same CoS pass through that tunnel 17.76

MPLS Introduction

Advanced Tunnel Parameters  P2P or P2MP  Single Service Only – When only one service will run on that tunnel  P2P Service Only – When MP2MP and P2MP Services will not run on that tunnel

18.76

MPLS Introduction

Selecting Endpoints – P2P Tunnel  Tunnels are unidirectional  Head = First selected endpoint  Tail = Second endpoint

1. Select the first Endpoint (Head)

2. Select the second Endpoint (Tail)

3. Complete &Activate

19.76

 If your service is bidirectional, you create 2 unidirectional tunnels

MPLS Introduction

Selecting Endpoints – P2MP Tunnel  P2MP Tunnels:  Head = First selected endpoint  All other endpoints are Tails

MPLS Introduction

FRR Tunnels

Global Services Division ECI Training Department 24.76

MPLS Introduction

Content  Creating and understanding the following MPLS schemes:  Link Protection  Node Protection

25.76

MPLS Introduction

FRR Link Protection  Link protection is to protect the link only For example: In the diagram below we have a link from A to B to be protected (NH -Next Hop) Bypass tunnel from A to B through C and D

A

B Protected tunnel

D

C Bypass tunnel 26.76

MPLS Introduction

Link Protection – Bypass First  Create a bypass tunnel with Link Protection

 Select Bypass  Select Link Protection  Fill in the tunnel parameters 27.76

MPLS Introduction

Creating a Bypass  Select endpoints  Select Protected Port

Bypass

 Complete and Activate 28.76

MPLS Introduction

Associating Tunnels If Bypass = first and protected = second THEN association is automatic

29.76

MPLS Introduction

Desired and actual protection  Protection desired - Protection desired for this tunnel  Protection actual – Quality of protection actually applying to a protected tunnel.

30.76

MPLS Introduction

Unprotected to protected tunnel When is Association required? If unprotected or protected was created before the bypass If Unprotected was created following a bypass

31.76

MPLS Introduction

Use Existing Bypasses  Option 1:

33.76

MPLS Introduction

Remember  Important! Tunnels are unidirectional  To create bi-directional Link Protection, the process must be done again from the other direction

A

Protected tunnel

B

Bypass tunnel 34.76

MPLS Introduction

FRR Node Protection  Node protection protects one link, and the node itself  Example: Traffic from A to B to C (NNH – Next next hop)

A C

B

D A

MPLS Introduction

Node Protection  Bypass tunnel via D and E protects against a failure in:  

Link A-C, or Node B sending traffic to C. Protected Node

C

Protected tunnel

D A

36.76

E Bypass tunnel

MPLS Introduction

Process to Node Protection  Create the Protected tunnel  Create the Bypass tunnel (Node Protection)  Verify in the Tunnel List window (In this case, association is automatic)

Creating Node Protection - Bypass

38.76

MPLS Introduction

Creating a Bypass  Select the end points and the specific port

Head

Tail Bypass

39.76

MPLS Introduction

Creating Node Protection  Create a Protected tunnel from A-C

 Trail List – to verify that the tunnel is protected, and which is its bypass 40.76

MPLS Introduction

Tunnel List for Tunnel Details  Update FRR Protection: From partial protection to Protection Full

41.76

MPLS Introduction

Tunnel List for Tunnel Details  To verify that the tunnel is protected, and which is its bypass

42.76

MPLS Introduction

Tunnel List for Tunnel Details Use existing Bypasses and create Bypasses for unprotected hops(full FRR protection not guaranteed): If a hop is not protected, create new bypasses, where possible. Full FRR protection is not guaranteed because if a bypass cannot be created for one or more hop, tunnel creation is still permitted.

Using existing Bypasses: LightSoft selects the bypass tunnels that provide protection using existing bypasses only.

Use existing Bypasses and guarantee full FRR protection: LightSoft provides protection using existing bypass tunnels only. Tunnel creation is only allowed if all hops are protected by existing bypasses.
