NOTE:
• Since a lar

e amount of information needs to be exchan
g
ed between a BSR and the other devices in the
PIM-SM domain, a relatively large bandwidth should be provided between the C-BSRs and the other
devices in the PIM-SM domain.
• For C-BSRs interconnected via a Generic Routing Encapsulation (GRE) tunnel, multicast static routes
need to be configured to ensure that the next hop to a C-BSR is a GRE interface. For more information
about multicast static routes, see “Multicast routing configuration.”
2. Configuring a PIM domain border
As the administrative core of a PIM-SM domain, the BSR sends the collected RP-Set information in the
form of bootstrap messages to all routers in the PIM-SM domain.
A PIM domain border is a bootstrap message boundary. Each BSR has its specific service scope. A
number of PIM domain border interfaces partition a network into different PIM-SM domains. Bootstrap
messages cannot cross a domain border in either direction
Perform the following configuration on routers that can become a PIM domain border.
Follow these steps to configure a PIM domain border:

Required
By default, no PIM domain border is
configured.
3. Configuring global C-BSR parameters
In each PIM-SM domain, a unique BSR is elected from C-BSRs. The C-RPs in the 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 PIM-SM domain. All the routers use the same Hash algorithm to get
the RP address corresponding to specific multicast groups.
Perform the following configuration on C-BSR routers.
