Abstract

A method supporting distributed resilient network interconnect (DRNI) in a link aggregation group at a network device is disclosed. The method starts with encapsulating a distributed relay control protocol data unit (DRCPDU) in a frame, wherein the DRCPDU includes a protocol data unit (PDU) structure. The PDU structure includes a type field indicating that the DRCPDU is for DRCP, a version field indicating a version number of the DRCP, and a set of type/length/values (TLVs) including: a terminator TLV indicating an end of the PDU structure, a portal information TLV indicating characteristics of the first portal, a portal configuration information TLV indicating configuration information of the first portal, a DRCP state TLV indicating variables associated with an intra-portal link (IPP), a home ports information TLV and a neighbor ports information TLV. The method continues with transmitting the frame encapsulating the DRCPDU from the network device to a neighbor network device.
