CLI Reference Guide
Use this command to configure the router to advertise itself as a candidate
bootstrap router (BSR). Use the no form of this command to remove this router
as a candidate for being a BSR.
Interface ID, from which the BSR address is derived, in order to make it a
candidate.
Configure hash mask length for RP selection. The range is 0 to 32. The mask
(32 bits maximum) that is to be logically ANDed with the group address before
the hash function is executed. All groups with the same seed hash (correspond)
to the same RP. For example, if this value is 24, only the first 24 bits of the group
addresses matter. Therefore one RP can be derived for multiple groups.
Configure priority for a BSR candidate. The range is 0 to 255. The BSR with the
larger priority is preferred. If the priority values are the same, the router with the
larger IP address is the BSR.
The router is not a BSR candidate.
HASH-MASK-LENGTH: 30
Priority : 64.
Global configuration
This command is valid in the SM mode
This command causes the router to send bootstrap messages to all its PIM
neighbors, with the address of the designated interface as the BSR address.
The following 2 conditions will cause BSR changes:
(1) Bootstrap Timer Expires
(2) Receive Preferred BSM.
In condition (1), the router is a Candidate-BSR, it will start to originate Bootstrap
messages and perform the BSR election. For condition (2), the router will store
the RP-Set from the preferred BSR.
Functionality of hash-mask is defined in RFC4601 4.7.2. The hash function is
used by all routers within a domain, to map a group to one of the RPs from the
matching set of group-range-to-RP mappings (all of this set has the same
longest mask length and the same highest priority). The algorithm takes as input
the group address, and the addresses of the candidate RPs from the mappings,
and gives as output, one RP address to be used.
