Subject: [c-nsp] Unicast RPF check in 3550/3750


Hi all,	
	Does anyone know if/when the 3550 or 3750 for that matter, will 
formally support unicast RPF check (ip verify unicast reverse-path...)? 
  Older 3550 IOS releases would take the command but do nothing with it,

and the fix for the "bug" was to remove the command from IOS :-)  More 
recent 3750s seem to take it, but its not listed anywhere in the docs as

a supported command.  I have not tried to see if it actually works on 
that platform.  I wouldn't think this would be a difficult feature to 
implement given the architecture of these switches.

Thanks
Chris
