Example: Configuring a Service Instance

Router (config)# interface gigabitethernet0/1

Router (config-if)#service instance 22 Ethernet [name]

Router (config-if-srv)# encapsulation dot1q 10

Router (config-if-srv)# bridge-domain 10

Example: Encapsulation Using a VLAN Range

Router (config)# interface gigabitethernet0/1

Router (config-if)#service instance 22 Ethernet

Router (config-if-srv)#encapsulation dot1q 22-44

Router (config-if-srv)# bridge-domain 10

Example: Two Service Instances Joining the Same Bridge Domain

In this example, service instance 1 on interfaces Gigabit Ethernet 0/1 and 0/2 can bridge between each other.

Router (config)# interface gigabitethernet0/1

Router (config-if)#service instance 1 Ethernet

Router (config-if-srv)# encapsulation dot1q 10

Router (config-if-srv)# bridge-domain 10

Router (config)# interface gigabitethernet0/2

Router (config-if)#service instance 1 Ethernet

Router (config-if-srv)# encapsulation dot1q 10

Router (config-if-srv)# bridge-domain 10

Example: Bridge Domains and VLAN Encapsulation

Unlike VLANs, the bridge-domain number does not need to match the VLAN encapsulation number.

Router (config)# interface gigabitethernet0/1

Router (config-if)#service instance 1 Ethernet

Router (config-if-srv)# encapsulation dot1q 10

Router (config-if-srv)# bridge-domain 4000

Router (config)# interface gigabitethernet0/2

Router (config-if)#service instance 1 Ethernet

Router (config-if-srv)# encapsulation dot1q 10

Router (config-if-srv)# bridge-domain 4000
