HP A6600 Configuration Manual page 339

To do...
3. Configure an interface as a
C-BSR.
4. Configure a legal BSR
address range.
Because a large amount of information will be exchanged between a BSR and the other devices in the
IPv6 BIDIR-PIM domain, a relatively large bandwidth should be provided between the C-BSRs and the
other devices in the IPv6 BIDIR-PIM domain.
Configuring an IPv6 BIDIR-PIM domain border
As the administrative core of an IPv6 BIDIR-PIM domain, the BSR sends the collected RP-Set information in
the form of bootstrap messages to all routers in the IPv6 BIDIR-PIM domain.
An IPv6 BIDIR-PIM domain border is a bootstrap message boundary. Each BSR has its specific service
scope. A number of IPv6 BIDIR-PIM domain border interfaces partition a network into different IPv6
BIDIR-PIM domains. Bootstrap messages cannot cross a domain border in either direction.
Perform the following configuration on routers that you want to configure as the IPv6 BIDIR-PIM domain
border.
To do...
1. Enter system view.
2. Enter interface view.
3. Configure an IPv6 BIDIR-PIM
domain border.
Configuring global C-BSR parameters
In each IPv6 BIDIR-PIM domain, a unique BSR is elected from C-BSRs. The C-RPs in the IPv6 BIDIR-PIM
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 BIDIR-PIM 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.
To do...
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure the hash mask
length.
4. Configure the C-BSR priority.
Use the command...
c-bsr ipv6-address [ hash-length
[ priority ] ]
bsr-policy acl6-number
Use the command...
system-view
interface interface-type
interface-number
pim ipv6 bsr-boundary
Use the command...
system-view
pim ipv6
c-bsr hash-length hash-length
c-bsr priority priority
