Hello,

I have all of my 3550's & 3560's running ospf and the 2950's & 2960's 
trunking to the 3550's and 3560's.  I would like for location 2960-14 to 
get its internet from Internet West and location 2960-07 to get its 
internet from Internet East.  Currently the 0.0.0.0 0.0.0.0 1.1.1.1 
(default gateway) is causing them both to resort to Internet west. (hope 
this is not to confusing)

Is there a way I can route the default gateway according to source 
networks without having to use PBR?  The reason I don't want to use PBR 
is because if there is any significant amount of traffic going through 
the 3550 or 3560 it will cause really high cpu utilization on the 
switch.  Is there some kind of static routing that can be done, or can 
use use the 0.0.0.0 0.0.0.0 1.1.1.1 route command according to source 
subnet?

eg:

if the source ip is 192.168.7.0/24 then use default gateway 0.0.0.0 
0.0.0.0 2.2.2.2 instead?

The other question is should I replace this switch with a router instead?

Thanks,
Dan.
