Configuring Ethernet Virtual Connection Bridge
Domain
Ethernet virtual connection (EVC) infrastructure is a Layer 2 platform-independent bridging
architecture that supports Ethernet services. This chapter provides procedures for configuring EVC
Bridge Domain (BD) and the features it supports on the Cisco Integrated Services Routers (ISR) G2.

Configuring EVCs on Cisco ISR G2 Router
Configuring an EFP and a BD on the Cisco ISR G2 Router
Configuring a service instance on a Layer 2 port creates an EFP on which you can configure EVC
features.
Note • You cannot use the same VLAN ID for encapsulating on a Layer 3 sub-interface and an EFP (service
instance) on a WAN interface.
• If there is a sub-interface and service-instance both configured on a WAN interface for untagged
traffic, then the traffic will always go to the main interface and the service-instance with untagged
traffic will not work.
Perform this task to configure an EFP.
