Hi, can you clarify this.
Please find attached simplified diagram.
My questions are:
a) If both 3750-Switch1 and 3750-Switch2 are configured as stackwise (cable), what should I consider and configure on port fa1/0/20 on both switches Switch1 and Switch2 if I want to connect (2) routers connected to different ISPs to the 3750 switches?
Should I run iBGP in the 3750 switch in order to make it pick Router1-ISP1 as the preferred route and Router2-ISP2 as my lower priority local preference? Is that it?
b) Is that the typical design you would do, or should I plan to connect another interface (fa0/1) of both routers to the other switch, so that could give me additional redundancy. Please let me know if you guys are doing that.
