Abstract:
1. A system, comprising: a first module that receives a packet, and synchronizes a group membership based on the packet; a second module that receives the synchronized group membership from the first module, and creates link aggregation group (LAG) entries for a primary switch and a secondary switch based on the synchronized group membership; a router that receives one or more join requests from the second module for adding a first interface link and a second interface link to the router; and a source coupled to the router that transmits traffic for the LAG, wherein the primary switch and the secondary switch receive traffic over an inter-switch link (ISL) port; wherein the second interface link is placed in a protocol independent multicast (PIM) pruned state based on a PIM assert message received from the second module by the primary switch and the secondary switch, and the second interface link is enabled upon the first interface link failing, wherein the second interface link forwards traffic and continues to forward traffic to an access switch even while remaining placed in the PIM pruned state.
