Configuring BSR Switches to Announce Scope-to-RP Mappings IPv6 BSR switches can be statically configured to announce scope-to-RP mappings directly instead of learning them from candidate-RP messages. A user might want to configure a BSR switch to announce scope-to-RP mappings so that an RP that does not support BSR is imported into the BSR. Enabling this feature also allows an RP positioned outside the enterprise's BSR domain to be learned by the known remote RP on the local candidate BSR switch. To configure BSR switches to announce Scope-to-RP mappings, perform this procedure:
Implementing IPv6 Multicast Configuring BSR Switches to Announce Scope-to-RP Mappings Command or Action Purpose Example: Device> enable Enter your password if prompted. Step 2 configure terminal Example: Device# configure terminal Enters global configuration mode. Step 3 ipv6 pim bsr candidate rp ipv6-address [hash-mask-length] [priority priority-value] Example: Device(config)# ipv6 pim bsr candidate bsr 2001:DB8:1:1:4 Configures a switch to be a candidate BSR. Step 4 ipv6 pim bsr candidate rp ipv6-address [group-list access-list-name] [priority priority-value] [interval seconds] Example:
Device(config)# ipv6 pim bsr candidate rp 2001:DB8:1:1:1 group-list list scope 6 Configures the candidate RP to send PIM RP advertisements to the BSR. Step 5 interface type number Example: Device(config-if)# interface GigabitEthernet 1/0/1 Specifies an interface type and number, and places the switch in interface configuration mode. Step 6 ipv6 multicast boundary scope scope-value Example: Device(config-if)# ipv6 multicast boundary scope 6 Configures a multicast boundary on the interface for a specified scope. Step 7 copy running-config startup-config (Optional) Save your entries in the configuration file. Implementing IPv6 Multicast 26
