HP A6600 Configuration Manual page 330

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 do...
1. Enter system view.
2. Enter interface view.
3. Configuring an IPv6 PIM
domain border.
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 do...
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure the hash mask
length.
4. Configure the C-BSR priority.
Configuring 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, during which no BSR election occurs. If the BSR state times out and no bootstrap
message is received from the BSR, a new BSR election process begins among the C-BSRs.
Perform the following configuration on C-BSR routers.
To do...
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure the BS period.
4. Configure the BS timeout.
