Subject: [pim] BSR doubt

Hello,
    I've few doubts on latest BSR draft (draft-ietf-pim-sm-bsr-01):

1. What to do if a NULL BSM is received (i.e. one with no group-addresses)? Should that be considered to be belonging to global scope (to make it backward compatible)? I have seen widely known vendors' implemetation sending NULL BSM.

2. On startup, initial state for configured scope zone is Pending BSR and the BS Timer is initialized to the BS Timeout value (130 sec) as per the spec. This results in BSR getting elected only after 130 seconds which seems to be a long period. What is the intention behind this long delay? Shouldn't C-BSR be sending BSR message at startup (with some random delay) and wait for some reasonable time (say 40 secs) to see if some other router is configured to be BSR.

Thanks
