Abstract
Ethernet OAM MEPs are automatically configured in a link state protocol controlled Ethernet network. A node operating in the link state protocol controlled Ethernet network receives a Link State PDU (LSP) containing a TLV having a MEP associated with the Ethernet MAC node ID of a second node in the link state protocol controlled Ethernet network, where the path between the first and second node includes a plurality of links. The node updates a forwarding table to indicate an association between the MEP ID and a Ethernet MAC node ID of the second node. An Ethernet OAM maintenance endpoint is produced in a link state protocol controlled Ethernet network by hashing a Sys-ID to produce a MEP; storing the MEP in a TLV; and forwarding the TLV over the link state protocol controlled Ethernet network in an LSP.
