problem with HSRP Multiple.

[elmoutaallikbillahtaha]

Hi Everyone

I have a problem while configuring Multiple HSRP, I have two routers, I've configured HSPR on it like this way : 

-----------------------------------------------------------------------------------------------

R1#show standby
Ethernet2/1 - Group 1
State is Active
2 state changes, last state change 03:36:49
Virtual IP address is 10.1.0.5
Active virtual MAC address is 0000.1111.5555 (MAC In Use)
Local virtual MAC address is 0000.1111.5555 (cfgd)
Hello time 3 sec, hold time 10 sec
Next hello sent in 1.760 secs
Authentication text, string "ccnp"
Preemption enabled, delay reload 90 secs
Active router is local
Standby router is unknown
Priority 105 (configured 105)
Group name is "hsrp-Et2/1-1" (default)
Ethernet2/2 - Group 2
State is Active
2 state changes, last state change 03:32:23
Virtual IP address is 10.2.0.5
Active virtual MAC address is 0000.2222.5555 (MAC In Use)
Local virtual MAC address is 0000.2222.5555 (cfgd)
Hello time 3 sec, hold time 10 sec
Next hello sent in 2.368 secs
Authentication text, string "ccnp"
Preemption enabled, delay reload 90 secs
Active router is local
Standby router is unknown
Priority 95 (configured 95)
Group name is "hsrp-Et2/2-2" (default)

----------------------------------------------------------------------------------------------

R2#sh standby
Ethernet2/1 - Group 1
State is Active
2 state changes, last state change 03:25:48
Virtual IP address is 10.1.0.5
Active virtual MAC address is 0000.2222.5555 (MAC In Use)
Local virtual MAC address is 0000.2222.5555 (cfgd)
Hello time 3 sec, hold time 10 sec
Next hello sent in 1.152 secs
Authentication text, string "ccnp"
Preemption disabled
Active router is local
Standby router is unknown
Priority 95 (configured 95)
Track interface Ethernet2/0 state Up decrement 20
Group name is "Subnet-1-" (cfgd)

-----------------------------------------------------------------------------------------------

A the end, I have a message ip 4 dupaddr duplicate address;

Mar  1 00:22:12.603: %IP-4-DUPADDR: Duplicate address 10.1.0.5 on FastEthernet0/1, sourced by 0000.1111.5555

that the routers detects duplication in the Virtual IP for both groups.

Do you have any idea please??

These lines found on both routers suggest that the routers are not seeing each others HSRP packets.

Active router is local
Standby router is unknown

Can you tell us how these routers are connected and also check to be sure that they are correctly connected?

It might be helpful to post the output of show arp from both routers.

Hi

to be honest, I'm preparing CCNP R&S, and I'm actually using GNS 3 with IOU solution to emulate my labs, I'm preparing ccnp SWITCH, so my two routers are using an L3 switch based on IOU all the ports were in the same vlan 1.

But this morning I changed my topolgy, I used a normal switch available on GNS3 and it is working.

So it's maybe an error with IOU. otherwise I'm suffering to prepare my certification without real materiels. 

If you have any proposition for a good emulator to prepare CCNP it will be wonderful.

Thank you SIR for your answer.

Taha.

If it does work with a normal switch and does not work with IOU then it sounds like a flaw with IOU. Best of luck with your CCNP studies.

Yes of curse

Thank again for your interaction Sir.

Have a nice day.

Hello

Local virtual MAC address is 0000.2222.5555 (cfgd)
Hello time 3 sec, hold time 10 sec
Next hello sent in 1.152 secs
Authentication text, string "ccnp"
Preemption disabled
Active router is local
Standby router is unknown
Priority 95 (configured 95)

I can see you have manually changed some defaults, the one that stands out for me is the VMAC for the Hsrp group

 - local virtual mac address
 - Group name ( differrent between the same group)
 - preemption is disabled for group 1

Can you share you HSRP configuration please

Lastly do you have any port-security applied that could negate peering and have you tired this WITHOUT authentication and/or using the default hsrp vmac?

Thanks for your answer, I had a problem with the IOU Switch, because when I used a normal GNS3 switch, it works now.

Thank you again. have a good day
