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

TCP/IP

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

DHCP and DNS Troubleshooting

http://www.guldmyr.com/blog/?p=2022 I’m going through how to set it up.

  • 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)

Routing

http://www.guldmyr.com/blog/?p=2022 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

Firewalls

  • 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

NAT

  • Describe NAT concepts

Upgrades

  • 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

http://www.guldmyr.com/blog/?p=2022 set up an area 0 OSPF

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