I am running a campus network with 1 6500 Switch as Core switch and 3560 Switch as distribution switches.
I have purchased another 6500 Switch for redundancy. I am confused how to integrate the new 6500 switch to the existing network. I wondering whether to configure HSRP or not. I am aware of HSRP configuration in routers with one interface. But here i have multiple VLANs are configured.
Kindly look at the diagram attached, and help me how to go with. Whether a dedicated cable is required between the switches and whether HSRP has to be configured or not?
Thanks in advance
Then you need to connect your 2 6500 switches together. This is usally done using an etherchannel link. The link can be either L3 or a L2 trunk. The ideal campus design is a L3 link but that requires that each access-layer switch and in your case distro switch has only one vlan on it or to put it another way you have not spanned vlans across access-layer/distro switches.
If you have spanned vlans then use a L2 etherchannel trunk between your 2 6500 switches and use HSRP.
