Since router 2 didn’t have a priority configured it becomes the active router since the default priority is 100 which is higher than that of router 1

Router2 is Missing the Priority

Router2:
interface GigabitEthernet0/0
ip address 192.168.1.254 255.255.255.0
duplex auto
speed auto
standby version 2
standby 111 ip 192.168.1.1
standby 111 priority 49
standby 111 track GigabitEthernet0/1
standby preempt

Higher priority will become the Active one

really good explanation and interesting

By: Lukasz

Lukasz — Tue, 25 Nov 2014 19:11:34 +0000

@Mixu
Switch will send the frame to both routers, the standby one will drop it.

To have this topology works we have to also assign IPs to interfaces on both routers (without it they will not communicate and both will be active from theur perspective).

Example:

Router1:

interface GigabitEthernet0/0
ip address 192.168.1.253 255.255.255.0
duplex auto
speed auto
standby version 2
standby 111 ip 192.168.1.1
standby 111 priority 50
standby 111 track GigabitEthernet0/1
standby preempt
!

Router2:

interface GigabitEthernet0/0
ip address 192.168.1.254 255.255.255.0
duplex auto
speed auto
standby version 2
standby 111 ip 192.168.1.1
standby 111 track GigabitEthernet0/1
standby preempt
!

Hope it’s more clear now.

what should be the priority to be active router. higher or lower priority?

By: james

james — Tue, 25 Nov 2014 11:33:10 +0000

@9tut. never mind. I have already figured it out. based on the example below. thanks

By: james

james — Tue, 25 Nov 2014 10:18:05 +0000

@9tut ……thanks 9tut for your explanation. I have question though.

What’s the criteria of electing the active router? or how does a router become an active router. in the given example why not the router 2 is the active router

If the Wan interface is down how router 1 will inform others that the wan link is down? there to add this command :
router1(config)#interface fastethernet 0/0
router1(config-if)#standby [standby group number] track [interface Serial number]

for exemple: #standby 1 track s0/0/0

if the serial 0/0/0 is down the router 1 will inform other router that it wan interface is down and give the hand to other router.

By: Mixu

Mixu — Wed, 12 Nov 2014 14:30:35 +0000

My comment was not an explanation, but a question. How does the switch know which port to forward to the active router if it has two identical vrtual macs pointing to two different ports in the mac address table?

Sanjay, you also bring up a good point. How does the standby router know when the active router WAN port is down if it still gets hellos from the active router?

Thanks for the explanation,but the question is how does the router identify that the second router wan port is working or not.The two routers are connected to switch through Fa0 port hence they can identify the hello packets but what about the wan connectivity.Lan port is fine but If the wan port of router 1 is not working then?????How does the router identify the condition.

By: Mixu

Mixu — Thu, 30 Oct 2014 23:49:38 +0000

If the switch caches the virtual mac in it’s mac address table, how does it know which port to forward it out of to get the the active router? The switch will have two macs identical with different ports numbers, one being the active router and one the standby.

Hi,
I think you also need to cover off things such as priority, and preempt. Why is a CPE active or standby, is it random or a config setting? Other features such as preempt which are very much real world and could be in the exam. Great starting article, I am doing my CCNA again, not held it since 2004.
