chance to become the BSR, you need to configure the same filtering policy on all C-BSRs in the IPv6
PIM-SM domain.
When you configure a C-RP, ensure a relatively large bandwidth between this C-RP and the other devices
in the IPv6 PIM-SM domain.
To configure a C-RP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
3. Configure an interface to be a
C-RP for IPv6 PIM-SM.
c-rp ipv6-address [ { group-policy
acl6-number | scope scope-id } |
priority priority | holdtime
hold-interval |
advertisement-interval
adv-interval ] *
No C-RPs are configured by
default.
4. Configure a legal C-RP
address range and the range
of IPv6 multicast groups to
which the C-RP is designated.
crp-policy acl6-number
Optional.
No restrictions by default.
Enabling embedded RP
The embedded RP feature can resolve the RP address directly from the IPv6 multicast group address of an
IPv6 multicast packets. This RP can replace the statically configured RP or the RP dynamically calculated
based on the BSR mechanism. Thus, the DR does not need to know the RP address beforehand.
Perform the following configuration on all routers in IPv6 PIM-SM domain.
To enable embedded RP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
3. Enable embedded RP. embedded-rp [ acl6-number ]
Optional.
By default, embedded RP is
enabled for IPv6 multicast groups
in the default embedded RP
address scopes.
NOTE:
The default embedded RP address scopes are FF7x::/12 and FFFx::/12. Here "x" refers to any legal
address scope. For more information about the Scope field, see "Multicast overview."
Configuring C-RP timers globally
To enable the BSR to distribute the RP-set information within the IPv6 PIM-SM domain, C-RPs must
periodically send C-RP-Adv messages to the BSR. The BSR learns the RP-set information from the received
messages, and encapsulates its own IPv6 address together with the RP-set information in its bootstrap
messages. The BSR then floods the bootstrap messages to all IPv6 routers in the network.
