摘要： A network device provides a selector list that includes indices of child nexthops associated with the network device, where each of the child nexthops is associated with a corresponding child link provided in an aggregated bundle of child links. The network device also receives an indication of a failure of a child link in the aggregated bundle of child links, and removes, from the selector list, an index of a child nexthop associated with the failed child link. The network device further receives probabilities associated with the child links of the aggregated bundle of child links. Each of the probabilities indicates a probability of a packet exiting the network device on a child link. The network device also creates a distribution table based on the probabilities associated with the child links, and rearranges values provided in the distribution table.

摘要： 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.

摘要： Techniques are described for maintaining a forwarding information base (FIB) within a packet-forwarding engine (PFE) of a router, and programming a packet-forwarding integrated circuit (IC) with a hardware version of the FIB. Entries of the hardware version identify primary forwarding next hops and backup forwarding next hops for the LSPs, wherein the packet-forwarding IC includes a control logic module and internal selector block configured to produce a value indicating a state of the first physical link. The selector block outputs one of the primary forwarding next hop and the backup forwarding next hop of the entries for forwarding the MPLS packets based on the value in response to the packet-processing engine addressing one of the entries of the FIB for the LSPs. Packets are forwarded with the PFE to the one of the primary forwarding next hop and the backup forwarding next hop output by the selector block.
