1. A method supporting a distributed resilient network interconnect (DRNI) in a link aggregation group at a network device, wherein the network device and a neighbor network device are included in a first portal of the link aggregation group, wherein the first portal is coupled via links of the link aggregation group with a second portal including of one or more remote network devices, and wherein the network device is communicatively coupled to the neighbor network device via an intra-portal port (IPP) using an intra-portal link (IPL), the method comprising:
receiving a distributed relay control protocol data unit (DRCPDU), wherein the DRCPDU includes neighbor network device's state information and configuration information, wherein the configuration information includes its operational aggregation key, gateway digest, and port digest;
determining whether at least some of the received configuration information is different from the configuration information of the network device;
determining whether a portion of the received operational aggregation key is identical to a corresponding portion of an operational aggregation key of the network device upon determining that the at least some of the received configuration information is different from the configuration information of the network device;
determining whether settings for being three system portal and gateway algorithms are the same as received values for being three system portal and gateway algorithms upon determining that the portion of the received operational aggregation key is identical to a corresponding portion of an operational aggregation key of the network device;
determining whether the received gateway digest is identical to a gateway digest of the network device upon determining that settings for being three system portal and gateway algorithms are the same; and
causing not to include a gateway conversation type/length/value (TLV) in a next DRCPDU to be transmitted by the network device to the neighbor network device upon determining that the received gateway digest is identical to the gateway digest of the network device.
