UMN:CLI User ManualV5812G370other neighbor PIM routers and compares its DR priority in those from neighbors. Therouter with the highest priority then is elected as the DR. In case of more than one routerwith the same highest priority value, the one with the higher IP address is elected. If noPIM hello message is received from the DR for a certain period of time, another DRelection is held.In PIM-DM, however, the DR only plays a role of the alternative IGMP querier using thisDR election when multiple routers exist with IGMPv1, since IGMPv1 does not define anyIGMP querier election process.To specify the DR priority on an interface, use the following command.Command Mode Descriptionip pim dr-priority<0-4294967294>InterfaceSpecifies the DR priority on an interface.0-4294967294: priority value (default: 1)no ip pim dr-priority<0-4294967294> Deletes the specified DR priority.no ip pim dr-priorityThe DR and the IGMP querier may be different routers in IGMPv2, while those aretypically the same router in IGMPv1. In IGMPv2, the DR is the router with the highest IPaddress on the subnet, whereas the IGMP querier is the router with the lowest IP address.9.3.2.3 Neighbor FilteringIf necessary, you can filter neighbor routers using access lists. When you enable thisfeature, PIM establishes adjacency without neighbor routers specified as deny in accesslists.To enable filtering neighbor routers in PIM, use the following command.Command Mode Descriptionip pim neighbor-filter {<1-99> |WORD} InterfaceEnables filtering neighbor routers in PIM.1-99: IP standard access listWORD: access list nameno ip pim neighbor-filter {<1-99>| WORD} Disables filtering neighbor routers in PIM.To display the information of PIM neighbor routers, use the following command.Command Mode Descriptionshow ip pim neighbor [detail]EnableGlobalBridgeShows the information for PIM neighbor routers.i
