scenario and Layer 2 Protocol Tunnel.
Note
EFPs and Ethernet over Multiprotocol Layer Switching (EoMPLS)
When you configure a pseudowire under a VLAN interface (for example, VLAN 33), the pseudowire becomes
a virtual Layer 2 port in that VLAN (VLAN 33), or bridge domain. In this bridge domain, you can configure
other types of Layer 2 ports, such as EFP portss. Switching functionalities, such as MAC address learning,
flooding, and forwarding to learned MAC addresses, apply to all the Layer 2 ports, including the pseudowire.
When a pseudowire is present in the same bridge domain as an EFP, you cannot configure the EFP with
the rewrite ingress tag pop 2 symmetric service instance configuration command. Other restrictions
about switching between EFPs or between EFPs also still apply.
Note
For more information about configuring pseudowire, see the Cisco ASR 920 Router Chassis Software
Configuration Guide.
Bridge Domain Routing
The switch supports IP routing and multicast routing for bridge domains, including Layer 3 and Layer 2 VPNs,
using the BDI model. There are the limitations:
•
You must configure BDIs for bridge-domain routing.
•
The bridge domain must be in the range of 1 to 4094 to match the supported VLAN range.
