24w3d: gateway address is one of our addresses.
24w3d: ICMP: bogus redirect from 10.105.28.26 - for 10.105.28.2 use gw 10.105.28.25
i received an error message like above, when i turned on debug ip icmp and tried to ping 10.105.28.2 which i configured at SW to have next hop as 10.105.28.25, why is it so? i have attached diagram.

Why have you configured the switch to have a next hop of itself?

Could you post the configs for each. Try turning off proxy arp see if that fixes the issue.

OK - here is what I see:-
SW1
-You have a DG of .9 which is itself.
-A route to .12 via .26 - but .12 is not on your diagram.
-You have a default route and an IP default gateway - you only need one.
You are not routing thru the firewall - so why have it.
RTB - has no default route, so it will not route anything to the internet.
Your whole design makes no sense - as all the connections are on Gig interfaces, then this would appear to be a LAN network. You do not need to use /30 IP subnets for a LAN - ideally you would use them for WAN topology.
I suggest you redesign - you have multiple single points of failure and no redundancy.
