What are the major issues in Meto Ethernet Multipoint deployment?
Most of the service providers delivering Metro Ethernet services today have constructed their networks out of Ethernet switches . The service is difficult to manage and sometimes unavailable due to spanning tree protocol instability , broadcast storm issues and other known problems with large Ethernet connectivity. These networks are also limited in the ultimate number of customers that can be deployed ; they can support only 4096 VLAN ids .One id is required per customer ,and since VLAN ids are globally significant they must all be unique withing the service provider . Providing such multipoint connectivity with Metro Ethernet thus is complex and unreliable , as a result of which multipoint to multipoint Metro Ethernet service across mutliple metros has been unrealistic to date .
