Probably means the 6500 does not have a route for that network. Can you do a "sh ip route 12.164.240.161" and see what you get ?

So 172.25.254.1 - can you do a "sh ip route 172.25.254.1"
If there is no route for that then that is your problem. If there is log on to the next hop and see if there is anything that would block the traceroute.

Hi,
Is 172.25.254.1 IP belongs to checkpoint firewall ??
Can you check is there any ACL is blocking your traceroute ?? can you enable logging and try to capture the log.

Hi
I have don’t have a gateway of last resort in this switch, so do you think because of that if I ping any external ip I am not getting the ip address in trace route

Hi Karthik,
Try traceroute with extended command from your switch like
6509switch#traceroute ip
Target IP address: 10.6.2.3
Source address: 10.1.30.1
Numeric display [n]: y
Timeout in seconds [3]:
Probe count [3]:
Minimum Time to Live [1]:
Maximum Time to Live [30]:
Port Number [33434]:
Loose, Strict, Record, Timestamp, Verbose[none]:
Type escape sequence to abort.

What my concern is when you are tracing a route your outgoing interface will be the source which in genral case are never routed, so try with mentioning the source ip and traceroute it should work.
Hope to Help !!

Hi Karthik,
As your routes for specific subnets are getting learned via peer end destination in that case you dont need,As suggested try the trace route with extended command with some source interface ip address which is advertise in routing.

Can you ping the destination IP?
Can you trace using a vlan has source on the cmd CLI, that should work.
