Hi

We discussed in the last pim meeting that this and the draft
draft-mankamana-pim-bdr-02.txt should have some text explaining what
is the difference between them, to make it less confusing for people.

What do you think about saying that "This draft allows DR election to
be sticky by not unnecessarily changing the DR when routers go down or
come up. This is done by introducing new PIM Hello options". Both this
draft, and the draft [draft-mankamana-pim-bdr] introduce a backup DR.
The latter draft does this without introducing new options, but does
not consider the sticky behavior.

The other draft should add text explaining the same.

What do you think?

Regards,
Stig
