DXS-3610 Series Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide Parameter PIM Passive Query Interval DR Priority Join Prune Interval BSR Domain Border Description operate in sparse mode, otherwise this multicast group will operate in dense mode. Select to enable or disable the PIM passive feature here. When the passive mode is enabled, the interface will neither send PIM messages out nor accept PIM messages from this interface. The router will act as if it is the only PIM router on the network. Use this feature only when there is only one PIM router on the LAN. Enter the interval at which hello messages are sent here. The range is from 1 to 18724 seconds. A PIMv2 router learns PIM neighbors via the PIM hello message. This feature configures the frequency of the hello message. Routers configured for IP multicasting send PIM hello messages to detect PIM routers. For SM, hello messages also determine the router to act as the designated router for each LAN segment. The configured query interval is also used as the value for hold time. By configuring a smaller period for the interval, the unresponsive neighbor can be discovered faster and thus the failover and recovery will become more efficient. By default, this value is 30 seconds. Select the Default option to use the default value. After selecting to use the Sparse Mode or the Sparse-Dense Mode, this parameter will be available. Enter the Designated Router's (DR) priority value here. The range is from 0 to 4294967295. A larger value represents the higher priority. In the Dense Mode (DM), the DR priority option will not be carried in the hello message. The router with the highest priority value will be the DR. If multiple routers are with the same priority status, the router with the highest IP address will be the DR. If there is a router that does not support the DR priority in its hello message on the LAN, all routers on the LAN will ignore DR priority and only use IP address to elect DR. By default, this value is 1. Select the Default option to use the default value. After selecting to use the Sparse Mode or the Sparse-Dense Mode, this parameter will be available. Enter the Join/Prune message interval value here. The range is from 1 to 18000 seconds. When configuring the Join/Prune interval, consider the factors, such as the configured bandwidth and expected average number of multicast route entries for the attached network or link. For the Sparse Mode (SM), routers will periodically send join messages based on this interval. The hold-time in a Join/Prune message is 3.5 times the join-prune-interval. The receiving router will start a timer based on this hold-time, and prune the interface if no join message was received on this interface. By default, this value is 60 seconds. Select the Default option to use the default value. Select to enable or disable the Bootstrap Router (BSR) domain border feature here. The feature only takes effect when the interface is PIM enabled. Use this feature on the interface that border with another domain to avoid the exchange of BSR messages across two domains. Click the Apply button to accept the changes made. Click the Back button to return to the previous window. PIM BSR Candidate This window is used to display and configure the PIM BSR candidate settings. This feature only takes effect when the interface has an IP address configured and is in the PIM sparse mode. This feature causes the router to send bootstrap messages to announce the IP address of the designated interface as the CBSR address. The hash mask is used by all routers within a domain, to map a group to one of the Rendezvous Points (RP) from the matching set of group-range-to-RP maps (this set all have the same longest mask length and same highest priority). The algorithm takes as an input the group address and the addresses of the candidate RPs from the maps, and gives as an output one RP address to be used. 310
