Abstract
Techniques are described for providing aliasing in an active-active multi-homed Provider Backbone Bridging Ethernet Virtual Private Network (PBB-EVPN) network. For example, PE devices of a multi-homed Ethernet segment may send packets received from the PBB-EVPN core network over the Ethernet segment to the customer device even if the receiving PE device has not learned the source MAC address of the CE device. In particular, the PE devices coupled to the multi-homed Ethernet segment may apply aliasing techniques in which a PE device performs a lookup of a BMAC address and the Customer Virtual Local Area Network (C-VLAN), instead of a lookup of a destination MAC address, to determine the path to send the data traffic.
