Hi all,
I support the adoption of this draft.
I reviewed this draft-xie-lsr-isis-sr-vtn-mt-03 and I think this draft
describes a good use case which realizes VPN+ by using existing IS-IS
extensions such as Multi-Topology, SR, and TE.
Thanks,

Hi, folks,
In this draft, MT-ID is resued as the control plane ID of VTN and advertise TE
attrributes for different VTNs. I think it is useful for carrier network, and I
support it to be adopted.

Dear Authors
Why was MT chosen and not MI for VTN underlay network slice underpinning.
MT instances has separate topology but not separate LSDB where MI Multi
instance RFC 6822 has a separate LSDB for resources isolation and I think
would be a better fit for VTN underlay provisioning.
