    Abstract: A plurality of line cards with each line card having a respective network forwarding engine and a respective outgoing interface (OIF) list and at least one fabric module communicatively coupled with each line card with each fabric module can have a respective network forwarding engine. The local OIF list can be asymmetrically programmed. The network forwarding engine of a line card can be configured to receive a multicast packet, compare a multicast address associate with the received multicast packet with entries in the local OIF list of the line card and forward the received multicast packet to at least one interface associated with the multicast address in response to the comparison resulting in a match.

    Abstract: Aspects of the subject technology relate to systems for arbitrating direct forwarder ("DF") instantiation between VPC peers used to facilitating the transport of bidirectional multicast traffic over a L2/L3 network boundary. In some aspects, arbitration of DF instantiation on a given VPC peer can include determining a first set of metrics for a first VPC switch, determining a second set of metrics for a second VPC switch, and determining, at the first VPC switch, whether to instantiate a designated forwarder (DF) operation based on a comparison of the first set of metrics and the second set of metrics. Methods and machine-readable media are also provided.

    Abstract: Methods and systems may be provided for detecting the moves of a multicast source. Sites that were previously designated as an active source may be immediately expired instead of waiting for route expiry. All multicast receiver sites may deterministically learn the new multicast source without additional LSP churn in ISIS for resolving the multicast source move conflict between the old and new source sites.

    Abstract translation: 可以提供用于检测组播源的移动的方法和系统。 以前指定为活动来源的站点可能会立即过期，而不是等待路由到期。 所有组播接收者站点可以确定性地学习新的组播源，而不需要在ISIS中进行额外的LSP流失来解决旧的和新的源站点之间的组播源移动冲突。

    Abstract: In one embodiment an approach is provided to efficiently program routes on line cards and fabric modules in a modular router to avoid hot spots and thus avoid undesirable packet loss. Each fabric module includes two separate processors or application specific integrated circuits (ASICs). In another embodiment, each fabric module processor is replaced by a pair of fabric module processors arranged in series with each other, and each processor is responsible for routing only, e.g., IPv4 or IPv6 traffic. The pair of fabric module processors communicates with one another via a trunk line and any packet received at either one of the pair is passed to the other of the pair before being passed back to a line card.

    Abstract translation: 在一个实施例中，提供了一种方法来有效地对模块化路由器中的线路卡和结构模块上的路由进行编程，以避免热点并因此避免不希望的分组丢失。 每个光纤模块包含两个独立的处理器或专用集成电路（ASIC）。 在另一个实施例中，每个结构模块处理器被彼此串联布置的一对结构模块处理器所替代，并且每个处理器仅负责路由，例如IPv4或IPv6业务。 这对交换矩阵模块处理器通过中继线相互通信，并且任何一个接收到的数据包在传递回线卡之前都会被传递到另一个数据包。
