Hi Peter,

To follow up on our offline discussions, we agreed that routers MAY do the optimizations listed below. Perhaps new text can be introduced in the next revision?

Thanks.

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
