I wish to implement HSRP for this design, however when I remove Router 2(R2) from the network, the SVR1 is unable to ping SVR2. I have HSRP configured on R2 and R3, and the routers show that the virtual IP configured is active and is on Active and Standby mode respectively. Could y'all find an issue with the design or should I try another protocol?

Hi there,
Can you share the config of the devices?
cheers,
Seb.

Can you specify so I can provide more? Below is the configuration for Router 2 and 3. I had 2 interfaces configured as I am unsure if the route coming from SVR 2 would need the HSRP too
Router 2:
interface FastEthernet0/0 (Btm of interface)
ip address 192.168.2.102 255.255.255.0
duplex auto
speed auto
standby 1 ip 192.168.2.101
standby 1 priority 105
standby 1 preempt
!
interface FastEthernet1/0 (Top of interface)
ip address 192.168.3.100 255.255.255.0
duplex auto
speed auto
standby 2 ip 192.168.3.103
standby 2 priority 105
standby 2 preempt
!
Router 3:
interface FastEthernet0/0 (btm of interface)
ip address 192.168.2.103 255.255.255.0
duplex auto
speed auto
standby 1 ip 192.168.2.101
standby 1 preempt
!
interface FastEthernet1/0 (top of interface)
ip address 192.168.3.101 255.255.255.0
duplex auto
speed auto
standby 2 ip 192.168.3.103
standby 2 preempt

Can we have the configs for SW1 and SW2?
I assume that the R1 has a route similar to:
! ip route 192.168.3.0 255.255.255.0 192.168.2.101 !
Likewise the default gateway for SVR2 is 192.168.3.103 ?
cheers,
Seb.

Yes. I have configured for Router1
ip route 192.168.3.0 255.255.255.0 192.168.2.101
ip route 192.168.3.0 255.255.255.0 192.168.2.103
!
I do not have any configurations on SW1 and SW2 as I'm unsure what to configure

Technically speaking the route for 192.168.3.0/24 should be directed at the HSRP VIP and not the interface IPs.
From R1 can you ping 192.168.2.103 ?
Regarding the switch configs, I've never used PT....but I guess all switchports are no shut and in the the same VLAN?
cheers,
Seb.

Update: I found out there is a problem that will arise, called Asymmetric loop. I added another Fast Ethernet connection between R2 and R3, and it solved the ping from SVR2 to SVR1. But now there is another problem. When I remove the cable from SW3 to R2, there is an intermittent ping from SVR2 to SVR1

I think you should upload your PT file and someone with the application installed (not me) will be able to help troubleshoot your topology.
cheers,

The forum does not allow for a Packet tracer extension

ZIP it up and post it.

1. show run R2
!

duplex auto
speed auto
standby 1 ip 192.168.2.101
standby 1 priority 105
standby 1 preempt
!
interface FastEthernet1/0
ip address 192.168.3.100 255.255.255.0
duplex auto

standby 2 preempt
!
2. show run R3
!
interface FastEthernet0/0
ip address 192.168.2.103 255.255.255.0 #change address
duplex auto
speed auto
standby 1 ip 192.168.2.101

FIX for 192.168.2.0/24:
On R2 you have wrong IP address on interface f0/0, HSRP need to create virtual IP address different from interface address.
Also change address on R3.
### change in R2
conf t
int f0/0
ip add 192.168.2.100 255.255.255.0
end
write
###
### change in R3
conf t
int f0/0
ip add 192.168.2.102 255.255.255.0
end
write
###
FIX for 192.168.3.0/24
In R2 and R3 I think you need to change HSRP address.
### change in R2
conf t
int f1/0
standby 2 ip 192.168.3.101
end
write
###
### change in R3
conf t
int f1/0
ip add 192.168.3.102 255.255.255.0
standby 2 ip 192.168.3.101
end
write
###
FIX for SVR2
### change in network configs
ip address 192.168.3.103
default gateway 192.168.3.101
FIX for R1
### change int f1/0 ip address and static route
conf t
int f1/0
ip add 192.168.2.103 255.255.255.0
no ip route 192.168.3.0 255.255.255.0 192.168.2.103
no ip route 192.168.4.0 255.255.255.0 192.168.2.101
end
write
###
FIX for R2 and R3
### change default route to SVR1 on R2 and R2
conf t
no ip route 192.168.1.0 255.255.255.0 192.168.2.100
ip route 192.168.1.0 255.255.255.0 192.168.2.103
end
write
###
Also delete connection between R2 and R3 on f6/0 interface
After this if you shutdown R2 or R3 everything works perfect.
Good luck.

Hello!
Can you check MAC address table in switches? Try to flush tables after you shutdown link to one of routers.
I've tried to do same thing and issue was in MAC table.

i do that , but i receives too many duplicated Error from each router
