Ping is (LSSR) not working as it should

Question

when trying to reach google from my PC, here's the trace route:

But when trying to use loose source routing ping, it always return "Request timed out."

ping -j 130.43.32.33 google.com (returns, Request timed out.)

and when I'm trying something like this, (192.168.1.1 is my router private ip and 192.168.1.3 is my PC private IP):

Please help me understand this whole thing about loose and strict source routing. (kindly provide examples)

Answer 1

Please help me understand this whole thing about loose and strict source routing

The idea behind Loose Source Routing (LSR) is to specify a Loose Source Route, which specifies a system through which the packets must pass through before proceeding on to their destination.

Unfortunately, source routing has a great potential for abuse, and therefore most network administrators block all source-routed packets at their border routers.

So, in practice, Loose Source Routes aren't going to work.

ping -j 130.43.32.33 google.com 
Request timed out

This probably fails because the owner of 130.43.32.33 has balocked source-routed packets (see above).

ping -j google.com 192.168.1.3
Bad route specified for loose source route.

This command won't work because you have the destination address before the intermediate destinations.

The following command might work, assuming source-routed packets are not blocked.

ping -j 192.168.1.3 google.com
