Peter,

If a given PE needs to get all notifications from all other PEs it is sufficient that it sends to local ABRs a single registration in a form of 0.0.0.0/0 <http://0.0.0.0/0> and be done.

my calculation was done for case where each PE needs to register only for 100 addresses of remote PEs. That's a small number but results in 100k registrations on each ABR, not even counting the inter-ABR ones.

But realistically speaking the case where services offered by a PE also exist on all 100K other PEs would be pretty rare.

Thx,
R.

    I don't think so. I'm talking about PE to ABR registrations only. I
    have
    not even counted the inter-ABR ones.
