Techniques are described for providing fast reroute for traffic in EVPN-VXLAN. For example, a backup PE device of an Ethernet segment is configured with an additional tunnel endpoint address ('reroute tunnel endpoint address') for a backup path associated with a second split-horizon group that is different than a tunnel endpoint address and first split-horizon group for another path used for normal traffic forwarding. The backup PE device sends the reroute tunnel endpoint address to a primary PE device of the Ethernet segment, which uses the reroute tunnel endpoint address to configure a backup path to the backup PE device over the core network. For example, the primary PE device may install the reroute tunnel endpoint address within its forwarding plane and one or more operations to cause the primary PE device to encapsulate a VXLAN header including the reroute tunnel endpoint address when rerouting the packet along the backup path.

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.
