Accept Any – The router does not know of an active BSR, and will
accept the first bootstrap message it sees as giving the new BSR's
identity and the RP-set.
■
Accept Preferred – The router knows the identity of the current
BSR, and is using the RP-set provided by that BSR. Only bootstrap

the current BSR will be accepted.
■
Candidate BSR – Bidding in election process.

Pending-BSR – The router is a candidate to be the BSR for the RP-
