Cisco HSRP Question
Hello Experts,
I have configured HSRP as shown in the attached topology. Can someone please take a look at the configs and let me know why ALSW-9 (ip address 100.1.1.3) cannot ping ALSW-10 (200.1.1.3) and vice-versa. Neither can it ping 200.1.1.2 on DLSW-5
Any thoughts will be greatly appreciated.
Cheers

The same problem as previous lab?
issue
#show ip route
on switches ALSW-9 and ALSW-10
if you have routing table then you need to configure at least default route on switches ALSW-9 and ALSW-10 or disable routing on switches by issuing
#no ip routing.

Predrag,
Thanks for responding.
I need to be clear on this.
One step at a time.
If I issue the command #no ip routing on on ALSW-0 & ALSW-10 will I be able to ping?

If I issue the command no ip routing on ALSW-9 & 10 what commands should I need to enable me to ping?
ASKER
if you have routing table
I do not have a routing table.

You have been very helpful, but to TBH you're being a little cryptic..
ASKER
I'm assuming you've seen the configs and you will have seen there isn't any routing.. so I don't know why you're asking me if there is any routing ??

Predrag,
Thanks for sticking with me on this.
One more thing in relation to this. I have shut down DLSW-4.
I have removed ip routing from switch ALSW-9 and DLSW-5.
I have also removed default route and default gateway from ALSW.
But I can now ping 200.1.1.2 on DLSW-5. , see logs
Can you explain why?

Typically that is the case of proxy ARP.
Proxy ARP can be used as replacement for routing. on many devices proxy ARP is enabled by default and it is considered security risk.

Can I get some help with this please.
Attached is the actual lab that my lab was built on.
You will see they were able to ping between switches, in their case ALS1 and ALS2
