Abstract
Techniques for handling multicast over link aggregated (LAG) interfaces and integrated routing and bridging (IRB) interfaces in a network device are described in which interfaces, at which a data unit is to be transmitted, may be represented hierarchically in which the LAG interfaces and IRB interfaces are represented as pointers. In one implementation, a device may determine routes for data units, where a route for a multicast data unit is represented as a set of interfaces of the device at which the data unit is to be output. Entries in the set of interfaces may include physical interfaces of the device and pointers to LAG interfaces or pointers to the IRB interfaces. The device may generate tokens to represent routes for data units and resolve the pointers to the LAG interfaces or the IRB interfaces to obtain physical interfaces of the router corresponding to a LAG or an IRB.
