1) define "functionality" 2) define "difference" in either case, the net result is the same. for inter-vlan forwarding on the same box, the integrated L3 switch will be faster because a) electrons don't have to travel as far and b) the stripping and rewriting of L2 headers can be more efficiently done ( if it is necessary at all ) on the integrated L3 switch. once in a while this group has entertained the discussion of the relative merits of L3 switches versus routers. it occurs to me that at the electron level integrated L3 switching is indeed superior to routing, or at least inter-vlan routing versus router on a stick. Howard - care to offer your insight here? I'm talking about things as they happen at the EE level. Router on a stick has to be "slower" and "less efficient" than integrated L3 for inter-vlan routing. OTOH, I don't see any advantage for an integrated L3 switch acting solely as a router, forwarding traffic from itself to another router down the wire, all other things being equal. > Thanks in advance! > > Maurice Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=62167&t=62166 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
