Service Instance / Bridge Domain

Hi Rene,

Can you explain how Service Instance work and Bridge Domain.


Hello Pornchai

A Service Instance is an entity that has been created in the Cisco IOS Carrier Ethernet infrastructure to address the requirements of ISPs providing Ethernet services to subscribers. The framework itself is called Ethernet Virtual Connection (EVC) and you can find out more about it here:

A Bridge Domain is a special type of logical interface that can be configured on a Cisco Router. Specifically, it is a logical interface that allows the flow of traffic between a Layer 2 bridged network and a Layer 3 routed network. More info about this can be found at this Cisco Documentation.

I hope this has been helpful!
