Hello Haris,
unless you add a multilayer switch you will have a single point of failure that is represented by the C7206VXR.
Spanning-tree protocol will handle layer2 redudancy. For each vlan traffic will flow from the router to the root bridge.
Another point of attention is how to be able to have the router connect to both switches.
Here a possible trick can be integrated routing and bridging IRB this will cause STP to run also on the router.
bridge N protocol ieee
bridge N route ip
int BVI N
ip address 10.10.N.2 255.255.255.0
standby N ip 10.10.N.1
standby N pri 100
standby N preempt
no shut
int vlan N
no ip addresss
bridge-group N
int g0/0
no ip address
int gi0/0.N
enc dot1q N
int g0/1
no ip address
int gi0/.N
enc dot1q N
this has to be done for each vlan.
this because you cannot configure two vlan subinterfaces with overlapping IP addresses on a router.
The best solution would be to have two routers or to add a multilayer switch capable of providing L3 services.
in this case the slight change can be that of adding an HSRP group in each vlan to provide default gateway redundancy.
Each access layer switch has to be connected with two uplinks one to current switch and the other one to the other switch.
If you add a multilayer switch it will be more performant then the C7206VXR so it is good to have it master of each HSRP group
int vlan N
ip address 10.10.N.3 255.255.255.0
standby N ip 10.10.N.1
standby N pri 105
standby N preempt
Also towards the servers you should deploy an HSRP group and one link of the server has to be connected directly to new layer3 switch.
Hope to help
Giuseppe
