Hi Authors and Chairs,

Regarding remote LFA draft, I would hope to see some points addressed in the 
draft before going to WGLC.
- It would be good to add some simulation results about how much TLDP session 
are required (TX and TX+RX), this in order to make people aware on how much 
rLFA may impact their TLDP session scaling

- We already raised the point some months ago about possibly "interop" issues 
in the following cases :
    * PLR choose a PQ which is not able to accept TLDP session : we verified it 
in a lab, and we can clearly fall into such situation in a live network, 
leading to protection not available.

    * PQ having multiple IP addresses /32 attached, so which one would be used 
to establish TLDP session ? Current implementations are using some heuristics 
and it would be good to document this

- Current text states that rLFA is computed only when LFA are not available and 
our analysis pointed that this is really not a good idea as in term of 
manageability rLFA alternate may be better than LFA alternate. It would be good 
that rLFA draft points to potential manageability issues and refers to the 
appropriate draft.


Thanks,

Best Regards,

Stephane
