To specify the DR priority on an interface, use the follow-ing command.Command Mode Descriptionip pim dr-priority<0-4294967294>Interface[VLAN]Specifies 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 are typi-cally the same router in IGMPv1. In IGMPv2, the DR is the router with the highest IP ad-dress on the subnet, whereas the IGMP querier is the router with the lowest IP address.10.3.2.3 Neighbor FilteringIf necessary, you can filter neighbor routers using access lists. When you enable this fea-ture, PIM establishes adjacency without neighbor routers specified as deny in access lists.To enable filtering neighbor routers in PIM, use the following command.Command Mode Descriptionip pim neighbor-filter {<1-99> |WORD} Interface[VLAN]Enables 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] EnableGlobal Shows the information for PIM neighbor routers.10.3.2.4 PIM Join/Prune Message Group FilteringIf necessary, you can filter PIM join/prune messages from separate group using accesslists. When you enable this feature, a specified PIM group of PIM join/prune messagesfrom the trusted neighbor are denied by a specified range of access lists.To enable PIM group filtering, use the following command.Command Mode Descriptionip pim group-filter {<1-99> |WORD} Interface Enables PIM group filtering to block PIM join/prunemessages using a specified access list.i
