How to avoid this ,also can i make all the vlan gateway in core switch ,and make trunk allowed all vlan .14,20,10 will it communicate each other  

i wants to make it static ,and same time between can i make it trunk link,with simple ip routing command will the issue resolved ?just asking    

so between layer 3 swithed do we needs to add a another network right ? then configure static route <<<172.16.10.1 and 10.2 between gateway >>>to vlan 20 traffic <<ip route 192.168.20.0 255.255.255.0 172.16.10.2 >>>.is this static route enough
