Operating rules for static RPs

  • Static RPs can be configured on the same routers as C-RPs.

  • Where a C-RP and a static RP are configured to support the same multicast group(s), the C-RP takes precedence over the static RP unless the static RP is configured to override the C-RP. (See Supporting a static RP as primary.)

  • Any static RP in a domain must be configured identically on all routers in the domain. Otherwise, some DRs will not know of the static RP and will not forward the appropriate multicast traffic, and some routers will not know where to send Joins for the groups supported by static RP.

  • Up to four static RP entries can be configured on a router. Each entry can be for either a single multicast group or a range of contiguous groups.

  • Only one interface can be configured as the static RP for a given multicast group or range of groups. For example, a properly configured PIM-SM domain does not support configuring and to both support a multicast group identified as

  • Static RPs are not included in the RP-set messages generated by the BSR, and do not generate advertisements.

  • If a static RP becomes unavailable, it is necessary to remove and/or replace the configuration for this RP in all routers in the domain.
