I have a 2600(ISP1) router which is connected to Fa1 of 2948G and a 3600(ISP2) connected to Fa2 of 2948G. The port Gig49 is connected to 3500 switch (group 1 for ISP1) and Gig50 to another 3500 switch (group 2 for ISP2). The first thing that I did was use the 2948G as a layer 2 switch and it worked out fine. My question is I want to use the 2948G as a layer 3 switch to maximize its potential but with the same topology. I only have 2 IP blocks for two different ISPs (ISP 1 and ISP 2). What should be my next step?, I configure the 2948G with IP uplink-redirect, and my problem was all my workstations and servers won't go thru to the internet. Please see attachements for reference of my physical topology. I'm a little confused with the routing protocol that will be used. Kindly guide me with this..A little help or advise is much highly appreciated.
