Abstract:

Exemplary systems, methods, apparatuses, and computer-readable media are provided for enabling PIM Assert re-election to be triggered to honor network configuration changes. Upon receipt of a PIM Join message for a multicast group, a router can enter a “Join” state and start an Expiry-Timer. Thereafter, the router may determine that it is an Assert-Loser for the multicast group via a PIM Assert election mechanism. At the expiration of the Expiry-Timer, instead of transitioning to a “No-Info” state and removing state for the multicast group, the router can, due to its status as the Assert-Loser for the multicast group, remain in the “Join” state and re-start the Expiry-Timer. Upon a later configuration change, the router can now automatically trigger a PIM Assert re-election, which can lead to the router potentially becoming the Assert-Winner without requiring a manual, traffic-disrupting intervention.

Abstract:

A method in a gateway router is described. The method includes receiving traffic with a destination of a virtual internet protocol (VIP) address corresponding to a scalable VIP appliance; selecting a point-to-point VIP tunnel associated with the VIP address, wherein the point-to-point VIP tunnel encapsulates a point-to-point link between the gateway router and the scalable VIP appliance; separating one or more packets within the traffic; classifying each of the one or more separated packets based on one or more indicators of the one or more separated packets; and forwarding each of the one or more separated packets to one of one or more IP tunnels based on the classification of each of the separated packets, wherein the one or more IP tunnels are connected to the scalable VIP appliance and wherein the one or more IP tunnels comprise a forwarding tunnel group associated with the point-to-point VIP tunnel.
