Is it the right approach to do spantree-load balancing with HSRP redundancy I have 4 users Vlans tied to subnets, vlan 10 172.16.10.0 vlan 11 172.16.11.0vlan 20 172.16.20.0 vlan 21 172.16.21.0 Server Farm Vlans vlan 101 172.16.101.0vlan 102 172.16.102.0 users vlans are connected back to (2) 6509 switches as well as server farms vlans. All of the ports between the switches will be trunk ports USER'S VLANS (1) 6509 (2) 6509set spantree root 10 20 set spantree root 11 21 set spantree root 11 21 secondary set spantree root 10 20 secondary int vlan 10 int vlan 10ip address 172.16.10.2 255.255.255.0 ip address 172.16.10.3 255.255.255.0 standby 1 ip 172.16.10.1 preempt standby 1 ip 172.16.10.1standby 1 priority 110 standby 1 priority 100 int vlan 20 int vlan 20ip address 172.16.20.2 255.255.255.0 ip address 172.16.20.3 255.255.255.0stand! by 2 ip 172.16.20.1 preempt standby 2 ip 172.16.20.1standby 2 priority 110 standby 2 priority 100 int vlan 11 int vlan 11ip address 172.16.11.2 255.255.255.0 ip address 172.16.11.3 255.255.255.0standby 3 ip 172.16.11.1 standby 3 ip 172.16.11.1 preempt standby 3 priority 100 standby 3 priorty 110 int vlan 21 int vlan 21ip address 172.16.21.2 255.255.255.0 ip address 172.16.21.3 255.255.255.0standby 4 ip 172.16.21.1 standby 4 ip 172.16.21.1 preempt standby 4 priority 100 ! standby 4 priority 110 For the server farm vlans: (1) 6509 (2) 6509set spantree root 101 set spantree root 102set spantree root 102 secondary set spantree root 101 secondary int vlan 101 int vlan 101 ip address 172.16.101.2 255.255.255.0 ip address 172.16.101.3 255.255.255.0standby 5 ip 172.16.101.1 preempt standby 5 ip 172.16.101.1standby 5 priority 110 standby 5 priority 100 int vlan 102 int vlan 102 ip address 172.16.102.1 255.255.255.0 ! ip address 172.16.102.3 255.255.255.0standby 6 ip 172.16.102.1 standby ip address 172.16.102.1 preemptstandby 6 priority 100 standby 6 priority 110 I will also connect 6509 switches together as trunk ports.
