Cisco Certified Network Associate (CCNA)

Cisco Certified Network Associate (CCNA)

CCNA certification is a second-level Cisco Career certification. This certification level validates the ability to install, configure, operate, and troubleshoot medium-size switched and routed networks, including implementation and verification of connections to remote sites in a WAN environment. Upon completion, CCNA candidates should be able to successfully carry out any number of essential networking maintenance and troubleshooting duties such as operating LAN, WAN and dial access services for small networks, as well as having good working knowledge of protocols such as IP, IGRP, Serial, Frame Relay, IP RIP, VLAN’s, Ethernet and Access Lists.
Candidates have the option of two path to get CCNA certified. Either take and pass two individual exams or alternatively, one larger, combined exam. The exam options are:
Combined exam: 640-802 CCNA - 90 minutes.
OR
Individual exams:
  • 640-822 ICND1 (90 minutes 40-50 questions) - CCENT certification
  • 640-816 ICND2 (75-90 minutes 40-50 questions)
It is higly recommended to students passing CCNA for the first time to use the "individual exams" path as it allows candidates to focus on one subject area at a time and then take the relevant exam when they feel ready. Additionally, the two-exam approach gives the candidate the opportunity to ease into the certification by taking the 640-822 ICND1 exam first.

HSRP Configuration

What is HSRP ?

HSRP (Hot Standby Router Protocol) is a redundancy protocol for setting up a fault-tolerant default gateway in a LAN environment. This is a Cisco proprietary protocol. The standard protocol is VRRP (Virtual Router Redundancy Protocol).


HSRP in Packet Tracer 6.0

HSRP is a new feature of Packet Tracer 6.0 . This protocol can be configured on every Cisco router available in Packet Tracer as well as on Cisco Catalyst 3560 layer 3 switch.
The following IOS commands are available :
  • standby  <0-4095> ip        Enable HSRP and set the virtual IP address
  • standby  <0-4095> preempt   Overthrow lower priority Active routers
  • standby  <0-4095> priority  Priority level
  • standby  <0-4095> timers    Hello and hold timers
  • standby  <0-4095> track     Priority Tracking

HSRP configuration using Cisco 2911 ISR routers

Packet Tracer 6.0.1 - HSRP topology example with Cisco 2901 ISR routers



Two network are configured for this tutorial :
  • Network 192.168.1.0/24
    • Router0 : 192.168.1.2 (GigabitEthernet 0/0)
    • Router1 : 192.168.1.3 (GigabitEthernet 0/0)

  • Network 192.168.2.0/24
    • Router0 : 192.168.2.2 (GigabitEthernet 0/1)
    • Router1 : 192.168.2.3 (GigabitEthernet 0/1)
Two HSRP groups are configured on the ISR routers :
  • HSRP Group 1 :
    • IP address : 192.168.1.1
    • Router0 with priority 120 (preemption enabled)
    • Router1 with HSRP default priority (100)

  • HSRP Group 2 :
    • IP address : 192.168.2.1
    • Router0 with priority 120 (preemption enabled)
    • Router1 with HSRP default priority (100)

Routers configuration

Router0 configuration

interface GigabitEthernet0/0
ip address 192.168.1.2 255.255.255.0
duplex auto
speed auto
standby version 2
standby 1 ip 192.168.1.1
standby 1 priority 120
standby 1 preempt
!
interface GigabitEthernet0/1
ip address 192.168.2.2 255.255.255.0
duplex auto
speed auto
standby version 2
standby 2 ip 192.168.2.1
standby 2 priority 120
standby 2 preempt

Router1 configuration:

interface GigabitEthernet0/0
ip address 192.168.1.3 255.255.255.0
duplex auto
speed auto
standby version 2
standby 1 ip 192.168.1.1
!
interface GigabitEthernet0/1
ip address 192.168.2.3 255.255.255.0
duplex auto
speed auto
standby version 2
standby 2 ip 192.168.2.1

Preemption is configured on Router0 using the standby X preempt commands. This router will always assume HSRP active state when it's online and if it has the highest HSRP priority in the network. The same configuration without the standby x priority 120 configuration on Router0 does not work and Router1 assumes the active state because it has a higher IP address configured.


Testing the configuration:

Packet Tracer 6.0 - HSRP active router (ISR 2911) with preemption enabled


Packet Tracer 6.0 - HSRP standby router (ISR 2911) with 2 groups


Router0 is active for both HSRP groups. Both routers detected each other correctly but the priority seems to be wrong (Standby router is 192.168.1.3, priority 120 should be Standby router is 192.168.1.3, priority 100 on Router0)

Testing HSRP configuration is Packet Tracer 6.0.1 (ping, tracert, arp)



Ping, traceroute and arp commands issued on Laptop0 confirms that the configuration is working. The IP packets are transiting through Router0 (192.168.1.2)


Known bug

HSRP can be configured the same way on Cisco 3750 multilayer switch vlan interfaces in Packet Tracer 6.0.1.

interface Vlan100
ip address 192.168.1.2 255.255.255.0
standby version 2
standby 1 ip 192.168.1.1
standby 1 preempt
!
interface Vlan200
ip address 192.168.2.2 255.255.255.0
standby version 2
standby 2 ip 192.168.2.1
standby 2 preempt

However :
  • Laptops can't ping the HSRP IP addresses configured on the multilayer switches
  • The packets are not forwarded between the 2 laptops if the HSRP address are the default gateways configured on both pc.
