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:
Contents
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
