Description
Number of high order 1s used to form a mask that is
ANDed with group address ranges of candidate RPs
to form a hash value. The mask determines the number
of consecutive addresses to assign across RPs with
the same group range. For PIM, this value ranges from
0 to 32 and has a default of 30. For PIM6, this value
ranges from 0 to 128 and has a default of 126.
Priority assigned to this BSR. The software elects the
BSR with the highest priority, or if the BSR priorities
match, the software elects the BSR with the highest
IP address. This value ranges from 0, the lowest
priority, to 255 and has a default of 64.
Description
Interface type and number used to derive the BSR
source IP address used in Bootstrap messages.
Multicast groups handled by this RP specified in a
prefix format.
Number of seconds between sending candidate-RP
messages. This value ranges from 1 to 65,535 and has
a default of 60 seconds.
Note
Priority assigned to this RP. The software elects the
RP with the highest priority for a range of groups, or
if the priorities match, the highest IP address. (The
highest priority is the lowest numerical value.) This
value ranges from 0, the highest priority, to 255 and
has a default of 192.
Note
Unless you specify bidir, this RP will be in ASM
mode. If you specify bidir, the RP will be in Bidir
mode.
Route-map policy name that defines the group prefixes
where this feature is applied.

Configuring BSRs
We recommend that you configure the
candidate RP interval to a minimum of 15
seconds.
This priority differs from the BSR
BSR-candidate priority, which prefers the
highest value between 0 and 255.
