Implementing IPv6 Multicast
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.
Beginning in privileged EXEC mode, follow these steps:
Configuring SSM Mapping
When the SSM mapping feature is enabled, DNS-based SSM mapping is automatically enabled, which
means that the switch will look up the source of a multicast MLD version 1 report from a DNS server.
You can use either DNS-based or static SSM mapping, depending on your switch configuration. If you
choose to use static SSM mapping, you can configure multiple static SSM mappings. If multiple static
SSM mappings are configured, the source addresses of all matching access lists will be used.
Note
To use DNS-based SSM mapping, the switch needs to find at least one correctly configured DNS server,
to which the switch may be directly attached.
Step 5
ipv6 multicast boundary scope scope-value
Example:
Switch(config-if)# ipv6 multicast boundary
scope 6
Configures a multicast boundary on the interface for a specified
scope.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.

Step 2
ipv6 pim [ vrf vrf-name ] bsr announced rp

[ priority priority-value ] [ bidir ] [ scope
scope-value ]
Example:
Switch(config)# ipv6 pim bsr announced rp
2001:DB8:3000:3000::42 priority 0
Announces scope-to-RP mappings directly from the BSR for the
specified candidate RP.
