same C-RP policy on all C-BSRs in the IPv6 PIM-SM domain because every C-BSR might become
the BSR.
When you configure a C-RP, reserve a relatively large bandwidth between the C-RP and the other
devices in the IPv6 PIM-SM domain.
The device might use the BSR RP hash algorithm described in RFC 4601 or in RFC 2362 to
calculate the RP for a multicast group. To ensure consistent group-to-RP mappings on all PIM
routers in the IPv6 PIM-SM domain, specify the same BSR RP hash algorithm on the routers.
To configure a C-RP:
Step
1. Enter system
view.
2. Enter IPv6 PIM
view.
3. Configure a
C-RP.
4. (Optional.)
Configure a C-RP
policy.
5. (Optional.)
Configure the
device to use the
BSR RP hash
algorithm
described in RFC
2362.
Configuring Anycast RP
IMPORTANT:
The Anycast RP address must be different from the BSR address. Otherwise, the other Anycast
member devices will discard the BSM sent by the BSR.
You must configure the static RP or C-RPs in the IPv6 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 member RP device.
•
As a best practice, configure no more than 16 Anycast RP members for an Anycast RP set.
•
As a best practice, use the loopback interface address of an RP member device as an RP
member address. If you add multiple interface addresses of an RP member device to an
Anycast RP set, the lowest IPv6 address becomes the Anycast RP member address. The rest
of the interface addresses become backup RP member addresses.
To configure Anycast RP:
