BCvRE - Brocade Certified virtual Router Engineer - Objectives

This post will be continuously updated with my short notes under each concept. It's not meant to be a replacement of the official training materials. I'm just starting out playing with the vRouter Core / open source version and installing it in a VM and set up some networks and firewalls is probably one of the best way to learn this. Learn by doing!

The Brocade Certified vRouter Engineer 2013 exam has these objectives:

Brocade Vyatta vRouter System Operations

  • Describe show command system usage
  • show - in operational mode shows status of components
  • show - in configurational mode shows the configurations
  • run show -  in configurational mode shows status of components
  • Identify key CLI operations
  • set/delete
  • copy (configs)
  • renew (new dhcp IP)
  • install (to disk)
  • Describe the commit and save processes

Ethernet Concepts

  • Identify Ethernet operations
  • Identify VLAN operations and settings
  • set interface ethernet eth0 vif vlanid # this creates eth0.vlanid a subinterface. This looks like a normal ethernet interface.
  • set interface pseudo-ethernet # these can be used if you want to set the MAC-address. Some features are not allowed for these peth devices though (VLAN, bonding).
  • Identify bonded interface operations
  • Two NICs on the same network
  • set interface bonding (IP address, mode)
  • set interface ethernet (bond-group)
  • Demonstrate knowledge of configuration and operation using show commands


  • Demonstrate knowledge of the relationship between Layer 2, IP and TCP/IP
  • Identify TCD and UDP differences
  • Identify address subnets

DHCP and DNS Troubleshooting

  • Describe troubleshooting of DHCP operations
  • show dhcp server leases
  • show log dhcp
  • Describe troubleshooting of DNS forwarding
  • monitor dns forwarding # I could not get anything into the log)
  • show dns forwarding # shows cache size for example)


bcvre-brocade-certified-virtual-router-engineer went through how to set up static routes

  • Identify uses for routing
  • Identify show commands for use with routing
  • Identify configuration of different types of static routes


  • Describe firewall operations and troubleshooting using show commands
  • Describe firewall rulebase operations
  • set firewall name name default-action
  • set firewall name name rule 1 destination/source
  • set firewall name name rule 1 action action
  • set interface bonding bond0 firewall in/local/out name name
    • in - into the router (matching on destination IP)
    • out - out from the router  (matching on source IP)
    • local - to the router itself


  • Describe NAT concepts


  • Describe the Brocade Vyatta upgrade process
  • 1. Install 6.5R1 to disk.
  • 2. add system image URL
  • 3. reboot
  • It is also possible to copy the config elsewhere and reinstall

Logging and Packet Captures

  • Identify logging options for firewall and NAT operations
  • set firewall name name rule num log enable
  • commit; exit
  • monitor firewall .. # and see matches to the rule.
  • Identify methods to verify operations and troubleshooting

OSPF Single-Area

bcvre-brocade-certified-virtual-router-engineer set up an area 0 OSPF

  • Describe OSPF show command output
  • Describe how to configure OSPF
