Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
3. Configure an interface as a
C-BSR. c-bsr ipv6-address [ hash-length
[ priority ] ] No C-BSRs are configured by
default.
4. Configure a legal BSR
address range.
bsr-policy acl6-number
Optional.
No restrictions by default.
NOTE:
Because a large amount of information needs to be exchanged between a BSR and the other devices in the
IPv6 PIM-SM domain, a relatively large bandwidth should be provided between the C-BSR and the other
devices in the IPv6 PIM-SM domain.
Configuring 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.
To configure an IPv6 PIM border domain:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configuring an IPv6 PIM
domain border.
pim ipv6 bsr-boundary
No IPv6 PIM domain border is
configured by default.
Configuring 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.
To configure C-BSR parameters globally:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
3. Configure the hash mask
length.
c-bsr hash-length hash-length
Optional.
126 by default.
