Hi Huanan, Thanks a lot for your review and comments.
My understanding is as Flex-Algo is defined by operator, different Flex-Algos can be defined for different purpose and with different constraints. Thus it is possible to use different Flex-Algos for both the normal case and the VTN case in the same network. Hope this helps.

The draft provides a useful mechanism to enable VTNs based on minor extensions to Flex-Algo and L2 bundle. One comment is: in one network, can some Flex-Algos be used for its traditional usage, and some other Flex-Algos be used for VTNs as described in this document? BR.

This document specifies a mechanism to use Flex-Algo together with small extensions to IS-IS L2 bundle to distribute the topology and resource attribute of SR based VTN. Your review and comments are appreciated. B.R.

Name: draft-zhu-lsr-isis-sr-vtn-flexalgo Revision: 01 Title: Using Flex-Algo for Segment Routing based VTN Document date: 2020-09-11 Group: Individual Submission Pages: 8 URL: https://www.ietf.org/id/draft-zhu-lsr-isis-sr-vtn-flexalgo-01.txt Status: https://datatracker.ietf.org/doc/draft-zhu-lsr-isis-sr-vtn-flexalgo/ Htmlized: https://datatracker.ietf.org/doc/html/draft-zhu-lsr-isis-sr-vtn-flexalgo Htmlized: https://tools.ietf.org/html/draft-zhu-lsr-isis-sr-vtn-flexalgo-01 Diff: https://www.ietf.org/rfcdiff?url2=draft-zhu-lsr-isis-sr-vtn-flexalgo-01 Abstract: As defined in I-D.ietf-teas-enhanced-vpn, enhanced VPN (VPN+) aims to provide enhanced VPN service to support the needs of enhanced isolation and stringent performance requirements. VPN+ requires integration between the overlay VPN and the underlay network. A Virtual Transport Network (VTN) is a virtual network which consists of a subset of network topology and network resources allocated from the underlay network. A VTN could be used as the underlay for one or a group of VPN+ services. I-D.dong-lsr-sr-enhanced-vpn defines the IGP mechanisms with necessary extensions to build a set of Segment Routing (SR) based VTNs. This document describes a simplified mechanism to build the SR based VTNs using SR Flex-Algo together with minor extensions to IGP L2 bundle. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
