I gave and cleared the Brocade Certified vRouter (Vyatta) Engineer Exam on 19th June.
Here’s a copy of my certificate:
Brocade Certified vRouter Engineer 2013 certificate
The Vyatta router practice sessions on the VMware Player helped a lot in addition to the SDN Trainings and the Nutshell guide provided by Brocade.
I decided to setup a simple firewall on my Vyatta VM router to block pings from another VM Host (Ubuntu 12.04). The network is entirely in the range 192.168.0.100/24. The Ubuntu Host IP is 192.168. 192.168.0.111
The Vyatta interface IP is 192.168.0.108
Ping between them is working prior to setting up firewall and gives destination port unreachable as soon as firewall is enabled via commit.
The firewall configuration is as below:
The configuration steps are simple and given below:
and then we need to apply the firewall to an interface which in this case is eth0.
After the above configurations are in place enter commit to apply them and ping will stop working.
We can also see the statistics in firewall section changing:
and also by name the firewall:
and also show firewall name *** statistics :
In my setup to set up DNS forwarding in the Vyatta router two steps needed to be followed. The first being configure an interface as a listen on interface. I configured this to be eth0 which is bridged to my Wifi rotuer. The second step is to configure a name server. I set this as the default gateway of the network i.e. the Address of the Wifi router.
Once done I was able to ping google from my vyatta VM.
Before an interface can be configured within Vyatta VM it needs to be added into the VMplayer settings. If this is not done it will not appear under Vyatta interfaces. The below snapshot shows my four interfaces which i added via the settings panel.
Adding an interface is simple. Select Network Adapter and click the +Add sign at the bottom. Bridged interfaces take their IP’s directly from you Guest’s dhcp server. NAT interfaces NAT their addresses from vmnet interfaces while Host Only interface type address can be set manually from within Vyatta. From within Vyatta the interfaces will appear as below:
The configuration will be as below:
I have configured all interfaces to take IP from DHCP servers instead of static IP.
There’s a number of steps that need to be done to set up your own mini lab of the Brocade Vyatta router. Firstly instead of re-inventing the wheel on my blog please follow all instructions given on the below blog post:
Instead of uploading to Datastore and using vcenter you can use the free VMplayer that VMWare offers.
After completing the installation steps you should be able to SSH into the vyatta VM and also make configuration changes. One additional step I would recommend is to hit the command save after running commit at the end of instruction set.
The Brocade Certified Vyatta Router Certification provides a good certified entry point into the fields of cloud computing and SDN.
