MikroTik MTCINE lab 1 of 12

eBGP with the v7 connection and template model

Fernvale Networks has its own AS number at last. Bring up its first eBGP session to an upstream with RouterOS 7's template, connection and session model, advertise Fernvale's address block, connect a stub customer that uses a private AS, and stop that private AS leaking to the Internet.

Run this lab

It needs Lite: its 4 nodes are set to 4 vCPU and 1,792 MB in total. That fits the free demo too.

The scenario

Fernvale Networks, the regional ISP you have been building since the MTCNA labs, has received its own autonomous system number, AS 64500, and the provider-independent block 198.51.100.0/24. Until now Fernvale used static routes to one upstream. Today it turns up its first eBGP session to the transit provider Northgate Transit (AS 64510), and connects its first BGP customer, Copperleaf Hosting, which uses the private AS 65010 and a /26 out of Fernvale's block.

Northgate has already configured its side of the session. You configure FV-EDGE and Copperleaf's router (Fernvale manages it for them). The hosts 198.18.0.1 and 198.18.1.1 on NORTHGATE stand for the Internet.

What you’ll practise

  • Explain autonomous systems, the path-vector idea and why BGP runs over TCP port 179
  • Build eBGP sessions with /routing bgp template and /routing bgp connection, and read /routing bgp session
  • Advertise a prefix with an address list and output.network, and know why it needs a matching route
  • Give a stub customer a default route only, with an output filter and default-originate
  • Remove a customer's private AS number before routes leave your AS

The tasks

  1. Look before you build
  2. Bring up eBGP to Northgate with a template and a connection
  3. Advertise Fernvale's block
  4. Connect a stub customer
  5. Remove the private AS

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 MikroTik MTCINE RouterOS v7 guided labs.

  3. Open 01 - eBGP with the v7 connection and template model 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.
