Configure a Designated Router Multiple PIM-SM routers might be connected to a single LAN segment. One of these routers is elected to act on behalf of directly connected hosts. This router is the Designated Router (DR). The DR is elected using hello messages. Each PIM router learns about its neighbors by periodically sending a hello message out of each PIM-enabled interface. Hello messages contain the IP address of the interface out of which it is sent and a DR priority value. The router with the greatest priority value is the DR. If the priority value is the same for two routers, then the router with the greatest IP address is the DR. By default the DR priority value is 192, so the IP address determines the DR. IP Version Task Command Syntax IPv4 Assign a DR priority value. ip pim dr-priority value IPv4 Change the interval at which a router sends ip pim query-interval seconds hello messages. IPv4 Display the current value of DR parameters. show ip pim interface IPv6 Assign a DR priority value. ipv6 pim dr-priority value IPv6 Change the interval at which a router sends ipv6 pim query-interval seconds hello messages. IPv6 Display the current value of DR parameters. show ipv6 pim interface Command Mode INTERFACE INTERFACE EXEC Privilege INTERFACE INTERFACE EXEC Privilege Create Multicast Boundaries and Domains A PIM domain is a contiguous set of routers that all implement PIM and are configured to operate within a common boundary defined by PIM Multicast Border Routers (PMBRs). PMBRs connect each PIM domain to the rest of the internet. Create multicast boundaries and domains by filtering inbound and outbound Bootstrap Router (BSR) messages per interface, using the [ip | ipv6] pim bsr-border command. This command is applied to the subsequent inbound and outbound updates. Already existing BSR advertisements are removed by timeout. Remove candidate RP advertisements using the clear [ip | ipv6] pim rp-mapping command. IP Version Task Command Syntax IPv4 Filter inbound and outbound Bootstrap Router ip pim bsr-border messages per interface. Remove candidate RP advertisements. clear ip pim rp-mapping IPv6 Filter inbound and outbound Bootstrap Router ipv6 pim bsr-border messages per interface. Remove candidate RP advertisements. clear ip pim rp-mapping Command Mode INTERFACE EXEC PRIVILEGE INTERFACE EXEC PRIVILEGE PIM Sparse-Mode | 717
