I'm working on network hardening...
I see if it's not use ip source route should be disable.... I would like to understand this to be able to know if it's used in our environnement or not...
Based on my read... it's look like have some relation to : "Local Source-Route Bridging", "Source-Route Translational Bridging", "Configuring Transparent Bridging" etc... (http://www.cisco.com/en/US/tech/tk331/tk660/tk610/tsd_technology_support_sub-protocol_home.html) but I'm not sure... can someone help me ?
Usage of IP source routing is described in RFC791. Cisco supports setting this header option in extended ping/traceroute, see http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080093f22.shtml#ext_troute. Neither of these documents might make it clear why you want to do this. Don't have a good suggestion for a document that explains "why".
"Do you know, if some of those product need "IP source route" ? "
Sorry, don't know.
