Hi Huaimo, it seems that you are suggesting using IP FRR and BIER FRR in the same domain. Is my understanding correct? Multi-layer protection in a network may work but, in my opinion, overcomplicated network management and operation. Would you expect that BIER FRR is more responsive to a network failure than IP FRR? What benefits could be in such a scenario? Which parameters, in your opinion, need to be coordinated between IP and BIER layers? I think that if the document includes the concurrent use of IP FRR and BIER FRR it should provide more detail on how such a scenario could be realized.
