virtual routers and critical reporters

Good day!

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.

This is circuit config:

circuit VLAN300

ip address 192.168.164.252 255.255.255.0

ip virtual-router 250 priority 110 preempt

ip redundant-vip 250 192.168.164.3

ip redundant-vip 250 192.168.164.4

ip redundant-interface 250 192.168.164.254

circuit VLAN164

ip address 192.168.160.76 255.255.255.240

ip virtual-router 10 priority 110 preempt

ip redundant-interface 10 192.168.160.78

circuit VLAN160

ip address 192.168.160.12 255.255.255.240

ip virtual-router 10 priority 110 preempt

ip redundant-interface 10 192.168.160.14

circuit VLAN161

ip address 192.168.160.28 255.255.255.240

ip virtual-router 10 priority 110 preempt

ip redundant-interface 10 192.168.160.30

Vlans 160 and 161 - server farms

Vlan 164 - VIP

Vlan 300 - uplink

Thanks!
