Method and system for synchronizing with neighbor in a distributed resilient network interconnect (DRNI) link aggregation group
First Claim
1. A method of updating operational states of a network device in a distributed resilient network interconnect (DRNI) of a link aggregation group, wherein the network device and a neighbor network device are included in a first portal of the link aggregation group, wherein the network device is communicatively coupled to the neighbor network device via an intra-portal port (IPP), and wherein each of the network device and the neighbor network device implements link aggregation including aggregation ports with a single aggregator of the first portal, the method comprising:
- initializing the network device for link aggregation, wherein the initialization includes setting variables of the network device for the first portal as configured by administrative settings;
receiving, by the network device, a distributed relay control protocol data unit (DRCPDU) from the neighbor network device;
determining, by the network device, that an operational state associated with the first portal is changed, wherein each of the network device and the neighbor network device includes a gateway of the first portal, and wherein the change of operational state associated with the first portal is based on the DRCPDU, which indicates that the neighbor network device'"'"'s IPP activity is active; and
updating, by the network device, a set of operational states of the network device for link aggregation from the administrative settings in response to the determination that the operational state associated with the first portal is changed, wherein the set of operational states of the network device for link aggregation includes an operational state of the gateway of the network device.

Abstract
A method of updating operational states of a network device in a distributed resilient network interconnect (DRNI) of a link aggregation group is disclosed. The method starts with initializing the network device for link aggregation, wherein the initialization includes setting variables of the network device for a first portal as configured by administrative settings, where the first portal includes the network device and at least one neighbor network device. The method continues with determining that an operational state associated with the first portal is changed and updating a set of operational states of the network device for link aggregation in response to the operational state change, where the set of operational states of the network device for link aggregation includes an operational state of the gateway of the network device.
