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.

A computer-implemented method for load balancing multicast traffic may include (1) identifying a plurality of switches that include at least a first switch that is connected to a second switch by a first path and a second path, (2) calculating a plurality of multicast distribution trees for distributing multicast traffic among the plurality of switches that includes (i) a first tree that includes the first path and whose root is different than the root of a second tree and (ii) the second tree that includes the second path, (3) receiving a plurality of multicast packets ingress to the plurality of switches at the first switch, and (4) using at least two of the plurality of multicast distribution trees to transmit the plurality of multicast packets from the first switch to the second switch. Various other methods, systems, and computer-readable media are also disclosed.
