■
Use the
hold-time
keyword to specify the amount of time the BSR keeps an RP
in its C-RP list if the BSR does not receive a C-RP advertisement message. The
default value is 150 seconds.
■
Use the
priority
keyword to specify a priority field value that the C-RP sends to
the BSR in C-RP advertisement messages. In the RP election process, the RP
with the lower priority value is preferred. The default value is 192.
■
Use the
interval
keyword to specify an interval, in the range 1–65535 seconds,
at which the C-RP sends advertisement messages to the BSR. The default value
is 60 seconds.
■
Example
host1(config)#
access-list 1 permit 227.0.0.0 15.255.255.255
host1(config)#
access-list 1 permit 228.0.0.0 15.255.255.255
host1(config)#
ip pim rp-candidate loopback 1 group-list 1
■
Use the
no
version to stop the router from acting as an RP candidate
■
See ip pim rp-candidate.
Migrating to BSR from Auto-RP
Migrating to BSR from auto-RP requires that you upgrade all PIM routers in the domain
to support BSR. However, until all routers are BSR-capable, continue to use auto-RP.
After all routers are BSR-capable, switch from auto-RP to BSR as follows:
1.
Use the
no ip pim send-rp-discovery scope
command to stop PIM in the network
by disabling all auto-RP mapping agents. This results in flooding to an empty
map.
2.
Reconfigure auto-RP mapping agents as candidate BSRs by using the
ip pim
bsr-candidate
command.
3.
Reconfigure auto-RP candidate RPs as BSR candidate RPs by issuing the
no ip
pim send-rp-announce
command and then issuing the
ip pim rp-candidate
command.
Switching to an SPT for PIM Sparse Mode
PIM sparse mode initiates multicasting using a shared tree. You can configure PIM
sparse mode to switch to an SPT when a source starts sending multicast messages,
or you can prevent PIM sparse mode from switching to an SPT. Multicasting over an
SPT might be more efficient than multicasting over a shared tree. (See “PIM Sparse
Mode” on page 82.)
ip pim spt-threshold
■
Use to specify when PIM sparse mode switches from a shared tree to an SPT.
■
Specify a nonzero integer or the keyword
infinity
to prevent PIM sparse mode
from switching to an SPT.
