The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
The PPPoE over BDI feature terminates PPPoE subscribers through a VXLAN L2 overlay network onto a Cisco Bride Domain Interface (BDI).
Service-policy queuing feature is not supported on BDI interface.
If there is a Qos policy with queuing feature configured on the virtual template then the policy will not be applied to the session.
PPPoE is a commonly used application in the deployment of digital subscriber lines (DSLs). PPPoE supports PPPoE on the client and the server.
Bridge domain interface (BDI) is a logical interface that allows bidirectional flow of traffic between a Layer 2 bridged network and a Layer 3 routed network traffic. Bridge domain interfaces are identified by the same index as the bridge domain. Each bridge domain represents a Layer 2 broadcast domain. Only one bridge domain interface can be associated with a bridge domain.
Bridge domain interface supports:
IP termination
Layer 3 VPN termination
Address Resolution Protocol (ARP), G-ARP, and P-ARP handling
MAC address assignment
PPPoE session request from PPPoE subscriber is terminated on CSR1000v through a VxLAN tunnel. The VxLAN tunnel between Edge Router and CSR1000v provides a layer2 connection for PPPoE packets.
