IP Multicast Snooping and Routing with Multi-Chassis Link Aggregation
First Claim
Patent Images
1. An aggregation switch in a multi-chassis system for performing Internet Protocol (IP) multicast snooping, comprising:
- a plurality of virtual fabric link (VFL) ports coupled to a VFL, wherein the VFL is connected to a remote aggregation switch, wherein the remote aggregation switch is active and in a separate physical chassis;
a plurality of external ports coupled to at least one edge node and at least one network node;
a database maintaining IP multicast snooping information; and
a chassis management module for receiving the snooping information via at least the external ports, storing the snooping information within the database and sharing the snooping information substantially in real-time with the remote aggregation switch via the VFL.

Abstract
Aggregation Switches connected via a virtual fabric link (VFL) are each active and able to perform at least limited IP multicast snooping. The resulting IP multicast snooping information is maintained internally within each Aggregation Switch and shared substantially in real-time therebetween via the VFL.
