HSRP Configuration
I am trying to configure HSRP based on the topology shown below.
However for some reason I cannot ping from PC0 to PC1 ip address.
I can ping from PC0 all interfaces of all routers , the interfaces facing PC0 as well as the interfaces on the other side...
I also can ping from each router the IP address of PC1
I do not think , being unable to ping from PC0 to PC1 is related to HSRP, but cannot pinpoint the issue.
I wonder if I need to configure HSRP on both sides of the Routers ??

I corrected the " standby 1 ip 19.168.0.10"
and
Removed the Default route....
I believe the reason I cannot ping from PC0 to PC1 but I can ping from PC1 to PC0, is because PC0 has a default gateway, which is the Virtual IP of the HSRP 192.168.0.10...However PC1 does not have a default gateway, because I have not configured HSRP on the interfaces facing PC1...
I believe that 's the case.

another thing I want to mention is :
** From PC0 I can ping the virtual IP address 192.168.0.10, but I cannot tell which router I received the reply from.
** I also may need help configuring Preempt, in case the Active router goes down... how can this be done?
I will appreciate it !!

I believe the reason I cannot ping from PC0 to PC1 but I can ping from PC1 to PC0, is because PC0 has a default gateway, which is the Virtual IP of the HSRP 192.168.0.10Nope. If PC0 can ping PC1, then PC1 has to be able to ping PC0 (unless there's an ACL or firewall involved). Pings are bi-directional. Which means that when PC0 pings PC1, it receives a packet (ICMP echo reply) from PC1.
However PC1 does not have a default gatewayBingo! There's a problem. But even bigger is that it appears both of the PC's have IP addresses on the same network. One should be 192.168.0.x and the other should be 192.168.1.x
** From PC0 I can ping the virtual IP address 192.168.0.10, but I cannot tell which router I received the reply from."show standby brief" will tell you which router is the active router.
** I also may need help configuring Preempt, in case the Active router goes down... how can this be done?First get it working. Then tune it.

""However PC1 does not have a default gateway"
<<Bingo! There's a problem. But even bigger is that it appears both of the PC's have IP addresses on the same network. One should be 192.168.0.x and the other should be 192.168.1.x>>
I fixed that...
But what will be the Default Gateway of PC1 ? I have configured HSRP for interfaces facing PC0 and set up their DG to be the Virtual IP of AVG... as you can see in the configuration, all router interfaces facing PC0 are in Standby group 1....
I wonder if I will have to configure all Router interfaces facing PC1 in Standby group 2 and create a Virtual IP ???
Though I can make any IP of any of the 4 routers to be the DG of PC1, however if one of the routers has a problem, there will be no ping reply from PC1
Any suggestion on what will be the DG of PC1 ??

OR
I guess I can configure Vlan Interface on Switch facing PC1 and assign it an IP address (192.168.1.x) and make that IP the DG of PC1

My first post said all about gateway and wrong IP address of PC1.
Even what default gateway address you can assign to PC1.
15 minutes after you asked your question :)

It worked !!
I configured HSRP on the other Network as well...and I can ping now from end to end on both ways...
