Switch Redundancy question !!
Hi,
I have 4 x 2950 switches plus 2 x 3750 (EMI) as core switch. Now I want to dual connect each L2 switch to both 3750 as a requirement of redundancy and 2 x 3750 will be inter-connected thru a UTP cable. STP will be enable on all 2950 & 3750, I also want both 3750 become active, how do I set it up without having L2 loop ? I read Cisco doc mentions HSRP is one of the solution. Does it mean if I enable HSRP on both
3750 ports, it'll avoid L2 loop ? Any other setting is required ?Another question : I saw many posts about L2 & L3 redundancy, I'm little confusing. I know STP is the solution for L2 redundancy & HSRP /routing protocol is the soluton of L3. If my L2 switch is capable of L3 switching, how do I configure the switch port to Layer 2 only, or to Layer 3.
many thanks :-)
