Information About PPPoE over BDI

PPPoE

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

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 over BDI

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.
