CCNP Service Provider lab 13 of 23

RSVP-TE and fast reroute

Build classic MPLS traffic engineering on IOS XR. Extend IS-IS, signal a tunnel with RSVP and a bandwidth reservation, protect a link with a backup tunnel, and fail it.

Run this lab

It needs Standard: its 4 nodes are set to 4 vCPU and 10,240 MB in total.

In your workspace: Shared, then CCNP Service Provider guided labs, then 13 - RSVP-TE and fast reroute

Run it on Standard from £5 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 4 vCPU and 10,240 MB together. Every lab plan includes every guided lab.

The scenario

Some of Fellgate Carrier's core still runs classic RSVP-TE. Segment routing is the future, but RSVP-TE reserves bandwidth and it's on the exam, and you'll find it in many provider networks. A wholesale customer has bought 20 Mbps from R1 to R4, with fast protection over the link from R1 to R2.

IS-IS is running on all four routers, and there's nothing else.

What you’ll practise

  • Enable the IS-IS TE extensions and read the TE topology
  • Signal an explicit and a dynamic path with RSVP
  • Steer traffic with autoroute announce
  • Build a next-hop backup tunnel and read the FRR database
  • Compare RSVP-TE with SR-TE

The tasks

  1. Extend the IGP
  2. Build the tunnel
  3. Protect a link with FRR
  4. Fail the protected link
  5. Compare with SR-TE

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder CCNP Service Provider guided labs.

  3. Open 13 - RSVP-TE and fast reroute and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
