HP FlexFabric 5950 series Configuration Manual page 143

A C-RP policy enables the BSR to filter C-RP advertisement messages by using an ACL that
specifies the packet source address range and multicast groups. It is used to guard against C-RP
spoofing. You must configure the same C-RP 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 C-RP
policy.
Enabling Auto-RP listening
This feature enables the device to receive Auto-RP announcement and discovery messages and
learn RP information. The destination IP addresses for Auto-RP announcement and discovery
messages are 224.0.1.39 and 224.0.1.40, respectively.
To enable Auto-RP listening:
Step
1. Enter system view.
2. Enter PIM view.
3. Enable Auto-RP listening.
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 a 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 restrictions and 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.
•
As a best practice, configure no more than 16 Anycast RP members for an Anycast RP set.
•
As a best practice, 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.
