### Supported Features

The current version of the SEFOS PIMv6 protocol supports these features:

- Multicast forwarding engine with clear separation between the control (routing) and multicast forwarding planes.

- Support for multiple components.

- RP and rooted shared trees (that is, multicast delivery trees), built and maintained by using periodic and triggered join and prune messages.

- Switching from RPT to SPT when a particular source generates heavy traffic.

- Unicast route changes.

- Configuration as BSR, propagating RP-set information into the network.

- IETF standards in RP and BSR elections.

- Configuration as a canditate-RP, which sends out the CRP information periodically to the BSR of the domain.

- Independent configuration as candidate-RP on each interface.

- Regular housekeeping functions such as neighbor discovery and timeout.

- Operations under multi-access networks by suppressing and overriding joins and prunes and by electing a single forwarder through asserts in sparse mode.

- Operations over point-to-point interfaces.

- Interoperation between components by using the rules specified in RFC2715. Each component can also function independently, which enables complete separation between components.

- GenID implementation, which is required to rebuild the multicast forwarding state when a router goes offline and restarts.

These features are configured by default:

- RP-related configurations

- Switching from RPT to SPT configurations

- BSR configurations

- PMBR configurations

- Interface configurations related to PIM components
