PIMv6 Administration Guide
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:
Switching from RPT to SPT configurations
