This eliminates the need to maintain the RP table through the RP statemachine. For routers that are the RP, the router is statically configured as the RP. This router is notrequired to be configured as a RP candidate.A designated router (DR) receiving a MLD report checks for the presence of an embedded RPaddress in the group address. If found, it uses this RP address as the target of the PIM Join that itinitiates and all subsequent protocol operations for this group.A designated router (DR) receiving a new multicast stream from a directly connected source,checks for the presence of an embedded RP address in the group address. If found, it uses this RPaddress as the unicast destination address of the PIM Register packets that it initiates.Other PIM routers that are also receiving PIM PDUs look into the group address for the presence ofan embedded RP address in the group address. If found, it uses this RP address for all its protocolneeds.Note that all 3 cases above assume that a static RP has not been configured locally. A staticallyconfigured RP has the highest precedence and will be used even if the group address contains anembedded RP address. When determining the RP, the software employs the following precedencetable with the highest precedence item listed first.1. Statically configured RP address2. Embedded RP address3. RP Set build using the RP state machineLeave Number of MLDv1 “leave” messages on the interface. (See 2_Ex for MLDv2.)Is_IN Number of source addresses that were included in the traffic.Is_EX Number of source addresses that were excluded in the traffic.2_IN Number of times the interface mode changed from exclude to include.2_EX Number of times the interface mode changed from include to exclude.ALLOW Number of times that additional source addresses were allowed or denied on the interface.BLK Number of times that sources were removed from an interface.This field Displays
