cisco 6500 redundant

[telefon45]

Hi

We have 2 buildings. At each building we have 1 cisco 6500. Each cisco 6500 is connected via etherchannel with 10G. Other switches at different building has connection both 6500 switches. We want 6500s work active-active. But we want a redundant system. If one of 6500s fails other 6500 maintain the network.

What do you suggest? Can we make STACK with 2 6500s.We do not want to configure both of 6500s.

Thank you

So you have these set up in an HSRP configuration, and your concern seems to be that one of them is basically doing "nothing"? Is that where you're coming from?

Both of them will work. each 6500 will maintain each building. With HSRP one of the switch will be at standby mode and not work.

I'm not following what you want to do. You can split up your vlans and have one router be active for say, the odd vlans, and the other router be the active router for the even vlans, or you could split it up based on what vlans are in those buildings. Either way, you can have multiple HSRP routers active, just not for the same vlans.

If you have multiple vlans, you adjust the spanning tree root so one switch is the root for say odd numbered vlans and the other switch is the root for even numbered vlans. That said, where is the content access by the end nodes?
