This section describes some of the features of the MPLS routing capabilities of TOTEM.
When loading a domain, you can choose to use bandwidth sharing or not. If you choose so, bandwidth will be shared among LSPs that are not activated at the same time (primary-backup sharing and backup-backup sharing, see ). However, Diffserv is not compatible with bandwidth sharing. If you decide to use bandwidth sharing, only one class type must be defined in the domain or an exception will be thrown. Even if multiple preemption levels are defined in the class type, those levels will be ignored and preemption will never occur.
