Configuring A Bsr - HPE FlexNetwork 5510 HI Series Configuration Manual

To configure a C-RP:
Step
Enter system view.
1.
Enter IPv6 PIM view.
2.
Configure a C-RP to provide
3.
services for IPv6 BIDIR-PIM.
(Optional.) Configure the
4.
device to use RP hash
algorithm described in RFC
2362.
Setting the maximum number of IPv6 BIDIR-PIM RPs
In an IPv6 BIDIR-PIM domain, one DF election per RP is implemented on all IPv6 PIM-enabled
interfaces. To avoid unnecessary DF elections, do not configure multiple RPs for IPv6 BIDIR-PIM.
This configuration sets a limit on the number of IPv6 BIDIR-PIM RPs. If the number of RPs exceeds
the limit, excess RPs do not take effect and can be used only for DF election rather than IPv6
multicast data forwarding. The system does not delete these excess RPs. They must be deleted
manually.
To set the maximum number of IPv6 BIDIR-PIM RPs:
Step
Enter system view.
1.
Enter IPv6 PIM view.
2.
Set the maximum number of
3.
IPv6 BIDIR-PIM RPs.

Configuring a BSR

You must configure a BSR if C-RPs are configured to dynamically select the RP. You do not need to
configure a BSR when you have configured only a static RP but no C-RPs.
An IPv6 BIDIR-PIM domain can have only one BSR, but must have a minimum of one C-BSR. Any
router can be configured as a C-BSR. Elected from C-BSRs, the BSR is responsible for collecting
and advertising RP information in the IPv6 BIDIR-PIM domain.
The BSR election process is summarized as follows:
Initially, each C-BSR regards itself as the BSR of the IPv6 BIDIR-PIM domain and sends BSMs
1.
to other routers in the domain.
When a C-BSR receives the BSM from another C-BSR, it compares its own priority with the
2.
priority carried in the message. The C-BSR with a higher priority wins the BSR election. If a tie
exists in the priority, the C-BSR with a higher IPv6 address wins. The loser uses the winner's
BSR address to replace its own BSR address and no longer regards itself as the BSR. The
winner retains its own BSR address and continues to regard itself as the BSR.
