G.8032v1 supported a single ring topology and G.8032v2 supports multiple rings/ladder topology. v1: G.8032 v1 supports a single ring topology. The v1 protocol is robust enough to work for unidirectional failure and multiple link failure scenarios in a ring topology. It allows mechanism to force switch (FS) or manual switch (MS) to take care of field maintenance scenario. v2: G.8032 v2 supports multiple rings/ladder topology. The v2 protocol also introduced other features such as Revertive/ Non-revertive mode after condition, that is causing the switch, is cleared, Administrative commands - Forced Switch (FS), Manual Switch (MS) for blocking a particular ring port, Flush FDB (Filtering database), and support of multiple ERP instances on a single ring.
