We have a lot of subnets configured on CSS in vip/interface redanduncy. Each CSS use uplink trunk to cat6k and between cat6k's used trunk too. So there is no loops in vlans. We don't want to use loop topology (for example connect each CCS with another cat6k) because of not correct team-work spanning tree on CSS and cat6k. So we want to use critical reporters and switching between master and backup CSS if uplink fails.
So what is the right configuration must be on both CSS? There are a lot of circuits for server farms, circuit for VIP address net and for uplink vlan and virtual router on each of them. Should I use differend VRID for each circuit or one for all? I want that if uplink fails all functionality switch to backup CSS.
