Hi authors,
Here are some comments about IP flexalgo as follows:
1.In Flex-Algo draft, there is description about using fast-rerouting
with Flex-Algo for SR-MPLS and SRv6 data plane. It is recommended that
similar text be added for IP Flex-Algo.
there is a similar text in section 8, but more work is required indeed.
One important note - TI-LFA requires some form of traffic steering. This
can be achieved by enabling both IP and SR flex-algo and use SR FA only
to protect IP FA, similar to protection of "unlabeled" traffic with SR
MPLS. Or some alternative mechanism for enforcing the traffic on the LFA
path is required.
2.Is Application-Specific Link Attribute (ASLA) MUST be used for IP
Flex-Algo path computation?
yes, the flex-algo application uses Flex-algo specific link attributes
as defined in base flex-algo draft.
thanks,
Peter

(Flex-Algorithm) In IP Networks" - draft-bonica-lsr-ip-flexalgo-01
This IP Flex Algorithm draft generated quite a bit of discussion on use
cases and deployment prior to IETF 109 and there was generally support
for WG adoption. This begins a two week WG adoption call. Please
indicate your support or objection to WG adoption on this list prior to
12:00 AM UTC on December 16^th , 2020. Also, review comments are
certainly welcome.
Thanks,
Acee
