1796BConfiguring an IPv6 PIM domain border
As the administrative core of an IPv6 PIM-SM domain, the BSR sends the collected RP-set information in
the form of bootstrap messages to all routers in the IPv6 PIM-SM domain.
An IPv6 PIM domain border is a bootstrap message boundary. Each BSR has its specific service scope.
IPv6 PIM domain border interfaces partition a network into different IPv6 PIM-SM domains. Bootstrap
messages cannot cross a domain border in either direction.
Perform the following configuration on routers that you want to configure as an IPv6 PIM domain border.

1797BConfiguring C-BSR parameters globally
In each IPv6 PIM-SM domain, a unique BSR is elected from C-BSRs. The C-RPs in the IPv6 PIM-SM domain
send advertisement messages to the BSR. The BSR summarizes the advertisement messages to form an
RP-set and advertises it to all routers in the IPv6 PIM-SM domain. All the routers use the same hash
algorithm to get the RP address that corresponds to specific IPv6 multicast groups.
Perform the following configuration on C-BSR routers.

1798BConfiguring C-BSR timers
The BSR election winner multicasts its own IPv6 address and RP-set information throughout the region that
it serves through bootstrap messages. The BSR floods bootstrap messages throughout the network at the
interval of the BS (BSR state) period. Any C-BSR that receives a bootstrap message retains the RP-set for
the length of BS timeout timer, during which no BSR election occurs. If no bootstrap message is received
from the BSR when the BS timeout timer expires, a new BSR election process begins among the C-BSRs.
Perform the following configuration on C-BSR routers.
