Abstract
An example system in accordance with an aspect of the present disclosure includes an inspection engine and a forwarding engine. The inspection engine is to identify whether a tunneled network packet is associated with the multicast group address and a VNI that is contained in the mapping table. The forwarding engine is to forward or discard the packet in response to whether the VNI is contained in the mapping table.

1-16. (canceled)
A network device comprising:
- a mapping table, to contain a mapping between an underlay network multicast group address and at least one virtual network identifier (VNI) corresponding to an overlay network;
- an inspection engine to identify whether a tunneled network packet received at the network device is associated with the multicast group address and a VNI that is contained in the mapping table;
- and
- a forwarding engine to forward the packet according to the multicast group address in response to the VNI being contained in the mapping table, and to discard the packet in response to the VNI not being contained in the mapping table.
A method comprising:
- identifying, by an inspection engine, whether a tunneled network packet is associated with a multicast group address and a VNI that is contained in a mapping table, wherein the mapping table is to contain a mapping between an underlay network multicast group address and at least one virtual network identifier (VNI) corresponding to an overlay network;
- forwarding, by a forwarding engine, the packet according to the multicast group address in response to the VNI being contained in the mapping table;
- and
- discarding, by the forwarding engine, the packet in response to the VNI not being contained in the mapping table.
A non-transitory machine-readable storage medium encoded with instructions, executable by a computing system to prune overlay network traffic, that when executed cause the computing system to:
- identify, by an inspection engine, whether a tunneled network packet is associated with a multicast group address and a VNI that is contained in a mapping table, wherein the mapping table is to contain a mapping between an underlay network multicast group address and at least one virtual network identifier (VNI) and associated at least one tenant address corresponding to an overlay network;
- forward, by a forwarding engine, the packet according to the multicast group address in response to the VNI being contained in the mapping table;
- and
- discard, by the forwarding engine, the packet in response to the VNI not being contained in the mapping table.
