HCIP-Datacom Core lab 10 of 14

IPv6 routing with OSPFv3 IS-IS and BGP

Connect two IPv6 domains: OSPFv3 on one side, IS-IS on the other, BGP4+ between them. Hosts use SLAAC, and a prefix filter keeps a management network private.

Run this lab

It needs Standard: its 6 nodes are set to 6 vCPU and 10,240 MB in total.

In your workspace: Shared, then HCIP-Datacom Core H12-821 guided labs, then 10 - IPv6 routing with OSPFv3 IS-IS and BGP

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 6 vCPU and 10,240 MB together. Every lab plan includes every guided lab.

The scenario

The Bristol and Glasgow networks are going IPv6-only for a pilot. Bristol's team likes OSPF, and Glasgow's likes IS-IS, and neither is changing. They'll stay separate domains and exchange routes over BGP4+ between R2 and R3. Glasgow's management network, 2001:DB8:44::/64, must not reach Bristol. All addresses are set: you add the routing.

R4650022001:DB8:FF::42001:DB8:34::4/642001:DB8:4::1/64 (PC2, SLAAC)IS-IS

R4's LoopBack1, 2001:DB8:44::1/64, is the management network.

What you’ll practise

  • Run OSPFv3 per interface and read its peers and routes
  • Add an IPv6 topology to IS-IS
  • Build a BGP4+ session and activate the IPv6 address family
  • Import IPv6 routes between BGP4+ and each IGP
  • Filter BGP4+ advertisements with an IPv6 prefix list

The tasks

  • Task 0: Load the starting configuration
  • Concept: OSPFv3 differences
  • Task 1: Run OSPFv3 on R1 and R2
  • Concept: SLAAC
  • Task 2: Give the PCs addresses
  • Concept: IS-IS for IPv6
  • Task 3: Run IS-IS on R3 and R4
  • Concept: BGP4+
  • Task 4: Build BGP4+ between R2 and R3
  • Task 5: Import BGP4+ into each IGP
  • Task 6: Keep Glasgow's management network out

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 HCIP-Datacom Core H12-821 guided labs.

  3. Open 10 - IPv6 routing with OSPFv3 IS-IS and BGP 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.
