hi Zsombor I certainly didnt mean a raw L2 switch device.
I certainly understand what the diffrence of default gateway means as opposed to a gateway. The method I listed was just to have opinions on if this way would work and for any better ideas. As suggested before creating another vlan would be more ideal. Yes agreed we know that floating statics are used when you have multiple ways to the same destination in which you can load balnace or use as a backup. In which if im correct in the case of load balancing you can load balance traffic to the same destinating but using differnt paths or links Thanks Zsombor regards, seun >From: Zsombor Papp >To: "gab S.E jones" >CC: [EMAIL PROTECTED] >Subject: Re: switch default gateway question [7:72288] >Date: Tue, 15 Jul 2003 09:01:06 -0700 > >If you mean a L2 device when you say "switch", then those don't forward >packets from the PCs based on default gateway.

When you set up all this, you can start moving the hosts >(ie. PCs *and* the switches) to the new subnets, and that's about it. > >Thanks, > >Zsombor > >At 09:47 AM 7/15/2003 +0000, gab S.E jones wrote: >>Basically I want to know how best to approach the situation.
