How to configure Bridge Domain For Two Different Ports

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.
