Tested these platforms: Solaris 8 -> sends src IP address of INTERFACE Cisco -> sends src IP address of INTERFACE Windows 2000, XP -> sends src IP address of INTERFACE Linux 2.6.0-pre1, 2.4.20, 2.4.21 -> sends src IP address of LOOPBACK Question: =BFWhat would be the implications of applying my patch or simil= ar to do linux behave like other OS? >Will open a TAC case tomorrow. I'm interested on testing this in Solaris. Same tests: Solaris 8 -> replies the ARP request Windows 2000, XP -> replies the ARP request Linux 2.4.21 -> replies the ARP request Cisco -> NOT replies the ARP request I will contact Cisco to see why they don't do and if it can be fixed in f= uture releases.
