CCNP ENARSI lab 14 of 35

VRF-Lite with OSPF, EIGRP and BGP

Split two routers into isolated corporate and lab networks that reuse the same addresses, run OSPF in one VRF and named EIGRP in the other over one trunk, and connect only the corporate VRF to a cloud provider with eBGP.

Run this lab

It needs Lite: its 3 nodes are set to 3 vCPU and 1,536 MB in total. That fits the free demo too.

In your workspace: Shared, then CCNP ENARSI 300-410 guided labs, then 14 - VRF-Lite with OSPF EIGRP and BGP

The scenario

Willowmere Engineering runs its corporate network and its product-test lab between two sites (R1 and R2). The lab team copies customer networks, so the lab uses the same addresses as the corporate LANs, and auditors require the two to be completely separated. Instead of buying separate routers and circuits, you'll use VRF-Lite: two routing tables per router, carried over the existing link as two VLANs. Only the corporate network may reach the company's cloud provider (R3), which peers with R2 using eBGP.

Routing design: OSPF process 10 in VRF CORP; **named EIGRP LABS, AS 20 in VRF LAB; BGP AS 65001** on R2 with an IPv4 VRF CORP address family towards R3. Route distinguishers: CORP 65001:10, LAB 65001:20.

What you’ll practise

  • Create VRFs with vrf definition, route distinguishers and the IPv4 address family
  • Carry two VRFs over one link with 802.1Q subinterfaces
  • Run OSPF and named-mode EIGRP inside VRFs
  • Peer eBGP inside a VRF and redistribute between BGP and OSPF in that VRF
  • Use VRF-aware show, ping and traceroute commands and prove isolation

The tasks

  1. Create the VRFs
  2. Put interfaces in the VRFs
  3. OSPF in VRF CORP
  4. Named EIGRP in VRF LAB
  5. eBGP to the cloud inside VRF CORP
  6. Prove isolation and connectivity

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 ENARSI 300-410 guided labs.

  3. Open 14 - VRF-Lite with OSPF EIGRP 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.
