CCIE Enterprise Infrastructure practice lab 6 of 8

Multicast and IPv6 services

Build two multicast domains: an anycast RP pair with MSDP and BSR in one, Auto-RP with a rogue to filter in the other, joined by MSDP with scoped boundaries, an RPF fix and SSM. Then add PIM for IPv6 with anycast RP, RA-based gateway redundancy, DHCPv6 and prefix delegation. A 3 to 4 hour practice lab.

Run this lab

It needs Standard: its 12 nodes are set to 12 vCPU and 6,400 MB in total.

In your workspace: Shared, then CCIE Enterprise Infrastructure practice guided labs, then 06 - Multicast and IPv6 services

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 12 vCPU and 6,400 MB together. Every lab plan includes every guided lab.

The scenario

Halden Freight streams depot camera feeds and software updates by multicast. The HQ network (Domain A) and the acquired factory (Domain B) have separate multicast designs, joined at one border, and a carrier link between them can't carry multicast at all. OSPF and OSPFv3 already run everywhere.

Rules for the whole lab

  • Don't change OSPF costs, addressing or the hosts' joins. RX3 is not yours: you can't change it.
  • No PIM on the carrier link, and no tunnels.
  • Multicast must not depend on dense mode, except what Auto-RP itself needs.
  • Don't remove the LAB-FAIL-* applets.

What you’ll practise

  • Design RP redundancy with anycast RP, MSDP and BSR
  • Run Auto-RP safely, with a mapping agent that ignores a rogue
  • Join two domains with MSDP, administrative scoping and a static multicast route
  • Use SSM and IGMPv3, and control which groups a LAN may join
  • Run IPv6 multicast with an anycast RP
  • Give a LAN IPv6 gateway redundancy with RAs, stateful DHCPv6 and a delegated prefix

The tasks

  • Section 1: Domain A: sparse mode with a redundant RP (26 points)
  • Section 2: LAN1 receivers (10 points)
  • Section 3: Domain B and the border (28 points)
  • Section 4: IPv6 multicast and LAN services (36 points)

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 CCIE Enterprise Infrastructure practice guided labs.

  3. Open 06 - Multicast and IPv6 services 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.
