Configuring PIMv6 for IPv6
– 632
it accepts the bootstrap message and forwards it. Otherwise, it drops the
message.
This router will continue to be the BSR until it receives a bootstrap message
from another candidate with a higher priority (or a higher IP address if the
priorities are the same).
To improve failover recovery, it is advisable to select at least two core routers in
diverse locations, each to serve as both a candidate BSR and candidate RP. It is
also preferable to set up one of these routers as both the primary BSR and RP.
Parameters
These parameters are displayed:
BSR Candidate Status
– Configures the switch as a Bootstrap Router (BSR)
candidate. (Default: Disabled)
VLAN ID
– Identifier of configured VLAN interface. (Range: 1-4093)
Hash Mask Length
– Hash mask length (in bits) used for RP selection (see
“Configuring a PIM6 Static Rendezvous Point” on page 633 and Configuring a
PIM6 RP Candidate” on page 635). The portion of the hash specified by the
mask length is ANDed with the group address. Therefore, when the hash
function is executed on any BSR, all groups with the same seed hash will be
mapped to the same RP. If the mask length is less than 32, then only the first
portion of the hash is used, and a single RP will be defined for multiple groups.
(Range: 0-32; Default: 10)
Priority
– Priority used by the candidate bootstrap router in the election
process. The BSR candidate with the largest priority is preferred. If the priority
values are the same, the candidate with the larger IP address is elected to be
the BSR. Setting the priority to zero means that this router is not eligible to
server as the BSR. At least one router in the PIM6-SM domain must be set to a
value greater than zero. (Range: 0-255; Default: 0)
Web Interface
To configure the switch as a BSR candidate:
1.
Click Routing Protocol, PIM6, SM.
2.
Select BSR Candidate from the Step list.
3.
Specify the VLAN interface for which this router is bidding to become the BSR,
the hash mask length that will subsequently be used for RP selection if this
router is selected as the BSR, and the priority for BSR selection.
4.
Click Apply.
