Command Remarks
3. Configure an interface as a
C-BSR.
c-bsr interface-type interface-number
[ hash-length [ priority ] ]
No C-BSRs are configured
by default.
4. Configure a legal BSR address
range.
bsr-policy acl-number
Optional.
No restrictions on BSR
address range by default.
NOTE:
• Because a lar
g
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 make sure the next hop to a C-BSR is a tunnel interface. For more information
about multicast static routes, see " Configuring multicast routing and forwarding."
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 you want to configure as a PIM domain border.
To configure a PIM domain border:

3. Configure a PIM domain border.
pim bsr-boundary
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 that corresponds to specific multicast groups.
Perform the following configuration on C-BSR routers.
