HP MSR2003 Configuration Manual page 108

The C-RPs periodically send advertisement messages to the BSR, which collects RP set information for RP
election. You can configure the interval for sending the advertisement messages.
The holdtime option in C-RP advertisement messages defines the C-RP lifetime for the advertising C-RP.
The BSR starts a holdtime timer for a C-RP after it receives an advertisement message. If the BSR does not
receive any advertisement message when the timer expires, it considers the C-RP failed or unreachable.
To guard against C-RP spoofing, configure a filtering policy on the BSR to define the legal C-RP address
range and the multicast group range to which the C-RP is designated. In addition, because every C-BSR
might become the BSR, configure the same filtering policy on all C-BSRs in the PIM-SM domain.
To configure a C-RP:
Step
1. Enter system view.
2. Enter PIM view.
3. Configure a C-RP.
4. (Optional.) Configure a legal
C-RP address range and the
multicast group range to which
the C-RP is designated.
Configuring Anycast RP
IMPORTANT:
The Anycast RP address must be different from the BSR address. Otherwise, the other Anycast RP member
devices will discard the BSM sent by the BSR.
You must configure the static RP or C-RPs in the PIM-SM domain before you configure the Anycast RP. Use
the address of the static RP or the dynamically elected RP as the Anycast RP address.
When you configure Anycast RP, follow these guidelines:
• You must add the device that the Anycast RP resides as an RP member to the Anycast RP set. The RP
member address cannot be the same as the Anycast RP address.
You must add all RP member addresses (including the local RP member address) to the Anycast RP
•
set on each RP member device.
HP recommends that you configure no more than 16 Anycast RP members for an Anycast RP set.
•
• HP recommends that you configure the loopback interface address of an RP member device as the
RP member address. If you add multiple interface addresses of an RP member device to an Anycast
RP set, the lowest IP address becomes the RP member address. The rest of the interface addresses
become backup RP member addresses.
To configure Anycast RP:
Step
1. Enter system view.
2. Enter PIM view.
