Loop-elimination in a network is provided by establishing a physical topology based domain within the network and restricting protocol data units that are received within the physical topology based domain from being consumed at a network node outside of the physical topology based domain, wherein the protocol data units include loop-elimination information. The loop-elimination technique may also include identifying a logical based domain that exists within the network and then restricting protocol data units that are received within the physical topology based domain and the logical based domain from being consumed outside of the physical topology based domain and the logical based domain.
