VyOS OSPF Practical Activity

Task description

You have the following topology:

                     +-----+
172.20.10.10---eth2--| rt1 |--eth1--10.10.0.10--+
                     +-----+                    |
                                                |
                                                | 
                     +-----+                    |
172.20.20.10---eth2--| rt2 |--eth1--10.10.0.20--|--10.10.0.0/24
                     +-----+                    |
                                                |
                                                |
                     +-----+                    |
172.20.30.10---eth2--| rt3 |--eth1--10.10.0.30--+
                     +-----+

Your objective is to configure OSPF between rt1/rt2/rt3 to enable connectivity between 172.20.x.0/24 networks.

0. Setup VirtualBox

Download from https://www.virtualbox.org/wiki/Downloads and install

1. Setup Vagrant

Download from https://www.vagrantup.com/downloads.html and install

2. Pull repository

git clone https://github.com/Astrarog/hse-vyos-ospf.git

3. Setup environment

cd hse-vyos-ospf
vagrant up

4. Configure virtual routers

Note: The password is "vagrant".

Configure hostnames and ip adresses

+-----+ | rt1 | +-----+	+-----+ | rt2 | +-----+	+-----+ | rt3 | +-----+
vagrant ssh rt1 configure set system host-name rt1 set interfaces ethernet eth1 address 10.10.0.10/24 set interfaces ethernet eth2 address 172.20.10.10/24 commit save	vagrant ssh rt2 configure set system host-name rt2 set interfaces ethernet eth1 address 10.10.0.20/24 set interfaces ethernet eth2 address 172.20.20.10/24 commit save	vagrant ssh rt3 configure set system host-name rt3 set interfaces ethernet eth1 address 10.10.0.30/24 set interfaces ethernet eth2 address 172.20.30.10/24 commit save

Configure ospf areas

+-----+ | rt1 | +-----+	+-----+ | rt2 | +-----+	+-----+ | rt3 | +-----+
set protocols ospf area 0 network 10.10.0.0/24 set protocols ospf parameters router-id 10.10.0.10 set protocols ospf area 1 network 172.20.10.0/24 commit save exit	set protocols ospf area 0 network 10.10.0.0/24 set protocols ospf parameters router-id 10.10.0.20 set protocols ospf area 2 network 172.20.20.0/24 commit save exit	set protocols ospf area 0 network 10.10.0.0/24 set protocols ospf parameters router-id 10.10.0.30 set protocols ospf area 3 network 172.20.30.0/24 commit save exit

5. Validate

+-----+ +-----+ | rt1 |--eth2--- OSPF ---eth2--| rt3 | +-----+ +-----+	+-----+ +-----+ | rt3 |--eth2--- OSPF ---eth2--| rt2 | +-----+ +-----+	+-----+ +-----+ | rt2 |--eth2--- OSPF ---eth2--| rt1 | +-----+ +-----+

6. Destroy VMs

vagrant destroy
