Hi Peter,

Sorry it’s a bit late but let me put it here anyway.

Without considering BIER, for LFA and TI-LFA, would we ever FRR or tunnel beyond area borders?

If the answer is no, then the inter-area redistribution could be simplified/reduced:


  *   BIER encapsulation information do not seem to be needed beyond the area border
  *   Prefixes for transit BFRs (those w/o non-zero BFR-IDs) do not need to be redistributed with BIER sub-TLV at all

I think the second optimization is especially more important.

Thanks.
Jeffrey
