NETGEAR 8800 Chassis Switch CLI Manual elected among all the candidates based on CBSR priority. To break the tie among routers with the same priority setting, the router with the numerically higher IP address is chosen. A NETGEAR 8800 switch can support up to 145 RPs per group when it is configured as a PIM BSR (bootstrap router). If more than 145 RPs are configured for a single group, the BSR ignores the group and does not advertise the RPs. Non-BSR switches can process more than 145 RPs in the BSR message. Example The following command configures a candidate bootstrap router on the VLAN accounting: configure pim cbsr vlan accounting 30 configure pim crp static configure pim crp static [none | ] { [0-254]} Description Configures a rendezvous point and its associated groups statically, for PIM sparse mode operation. Syntax Description ip_address none policy priority Specifies a static CRP address. Deletes the static rendezvous point. Specifies a policy file name. Specifies a priority setting. The range is 0 - 254. Default The default setting for priority is 0, which indicates highest priority. Usage Guidelines In PIM-SM, the router sends a join message to the rendezvous point (RP). The RP is a central multicast router that is responsible for receiving and distributing multicast packets. If you use a static RP, all switches in your network must be configured with the same RP address for the same group (range). NETGEAR 8800 switches support up to 50 RPs in a switch, and up to 180 groups within a single RP. If you configure more than 180 groups for a single RP, the switch does not process the groups added after the first 180. The policy file contains a list of multicast group addresses served by this RP. This policy file is not used for filtering purposes. As used with this command, the policy file is just a container for a list of addresses. So a typical policy file used for RP configuration looks a little different from a policy used for other purposes. Chapter 26. IP Multicast Commands | 1189
