In the previous post, I have shown how to configure a single port with single service instance. But when two different ports wants to communicate, how could it be possible by using EVC?
Switch (config)# interface gigabitethernet0/10
Switch (config-if)# switchport mode trunk
Switch (config-if)# switchport trunk allowed vlan none
Switch (config-if)# service instance 101 Ethernet
Switch (config-if-srv)# encapsulation dot1q 102
Switch (config-if-srv)# bridge-domain 103
Switch (config)# interface gigabitethernet0/11
Switch (config-if)# switchport mode trunk
Switch (config-if)# switchport trunk allowed vlan none
Switch (config-if)# service instance 101 Ethernet
Switch (config-if-srv)# encapsulation dot1q 102
Switch (config-if-srv)# bridge-domain 103
Switch (config-if)# service instance 101 Ethernet
Switch (config-if-srv)# encapsulation dot1q 102
Switch (config-if-srv)# bridge-domain 103
Golden Rules while configuring multiple instances in single port:-
1. All the instances must fall under same bridge domain.
2. All the service instance should have same dot1q encapsulation, if the dot1q encapsulation is not same in that case rewrite keyword is used.
In my next port I will explain about how to make communication possible in same bridge domain with different encapsulation dot1q.
SDN and NFV is the next phase of technology change which will help service provider to launch the services in single click. This is all about the programmability of the networks by using open source software defined network controller.

This is what I am currently doing and I will follow this script configuration to finish this task of assigning a bridge domain to two parallel domains.
