Abstract: The techniques describe directly forwarding a packet from an ingress packet forwarding engine to a particular destination packet forwarding engine (PFE) when internal packet load balancing may otherwise result in an increased number of fabric hops. For example, a source PFE may receive incoming packets destined for a router reachable only by a particular destination PFE (e.g., egress PFE). Rather than load balancing the incoming packets to a destination PFE that is likely to be a non-egress PFE, a source PFE obtains fabric path information associated with the egress PFE from a destination PFE such that source PFE may forward incoming packets directly to the egress PFE.

Abstract: In general, techniques are described for filtering duplicate broadcast, unknown unicast, and multicast (BUM) packets in a network in which EVPN traffic is tunneled, using a tunneling protocol such as VXLAN or NVGRE, over an IP core network to provide network virtualization overlay (NVO) between provider edge (PE) devices that operate as Network Virtualization Endpoints (NVEs) for the NVO/Virtual Tunnel Endpoints (VTEPs) for the tunneling protocol.
