Hi authors,

Here is one comment following the previous discussion on the mail list and the IETF meeting.

The IP Algorithm TLV is defined to advertise the IP Flex-Algorithm participation information, there is no separate TLV for IPv4 or IPv6 Flex-Algo participation. If some nodes participate in IPv4 Flex-Algo 128, and some of these nodes participate in IPv6 Flex-Algo 128, how to ensure that the path computed for IPv6 Flex-Algo will not use the nodes which only participate in IPv4 Flex-Algo 128?

Best regards,
Jie

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 16th, 2020. Also, review comments are certainly welcome.
Thanks,
Acee
