HP 6125G - Configuring a BSR

Command Remarks
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.
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 obtains 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.
Each C-RP encapsulates a timeout value in its C-RP-Adv messages. After receiving a C-RP-Adv message,
the BSR obtains this timeout value and starts a C-RP timeout timer. If the BSR fails to obtain a subsequent
C-RP-Adv message from the C-RP when the timer times out, the BSR assumes the C-RP to have expired or
become unreachable.
You must configure the C-RP timers on C-RP routers.

Command Remarks
1. Enter system view.
system-view N/A
2. Enter IPv6 PIM view.
pim ipv6 N/A
3. Configure the C-RP-Adv
interval.
c-rp advertisement-interval interval
Optional.
60 seconds by default.
4. Configure C-RP timeout time.
c-rp holdtime interval
Optional.
150 seconds by default.

common timers."
Configuring a BSR
An IPv6 PIM-SM domain can have only one BSR, but must have at least 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 PIM-SM domain.
Configuring a C-BSR
You should configure C-BSRs on routers in the backbone network. When you configure a router as a
C-BSR, be sure to specify the IPv6 address of an IPv6 PIM-SM-enabled interface on the router. The BSR
election process is as follows:
3. Initially, every C-BSR assumes itself to be the BSR of this IPv6 PIM-SM domain and uses its interface
IPv6 address as the BSR address to send bootstrap messages.
