Re: [Lsr] Using IS-IS Multi-Topology (MT) for Segment Routing based Virtual Transport Network

Trying to avoid piling on...but Peter is certainly correct that there is nothing in this draft that is normative. This may provide useful context for the protocol extensions defined in https://datatracker.ietf.org/doc/draft-dong-lsr-sr-enhanced-vpn/. As such the content would be better

Re: [Lsr] Using IS-IS Multi-Topology (MT) for Segment Routing based Virtual Transport Network

Hi, As Joel notes, it is true that enhanced VPNs require the use of specific underlay network resources, either dedicated or shared, but the this needs to be done without installing overlay VPN awareness in the P routers, which is inherently unscalable and operationally complex. Also, since

[Lsr] Slides for Interim Meeting

Hi presenters, Please send your slides to lsr-cha...@ietf.org before the end of this month (3/31). Thanks, Yingzhen ___ Lsr mailing list Lsr@ietf.org https://www.ietf.org/mailman/listinfo/lsr

Re: [Lsr] Using IS-IS Multi-Topology (MT) for Segment Routing based Virtual Transport Network

Hi Peter, As described in the abstract, the purpose of this draft is to define a simplified control plane mechanism to build SR based Virtual Transport Network (VTN), it is based on the combination of IS-IS Multi-Topology with other IS-IS extensions, e.g. the extensions for TE, SR and L2

Re: [Lsr] Using IS-IS Multi-Topology (MT) for Segment Routing based Virtual Transport Network

Hi, John: In your proposal, there is the following text “ the network controller SHOULD ensure that the IGP and TE metrics for these resources is higher than the metrics for the underlay network resources allocated to non-enhanced VPNs.” Considering these resources will span across the network

Re: [Lsr] Using IS-IS Multi-Topology (MT) for Segment Routing based Virtual Transport Network

In once sense, the statement is inherently true. A VPN technology without underlay support would seem to have significant difficulty in consistently meeting an SLA. Having said that much, the rest does not seem to follow. Yours, Joel On 3/26/2020 1:40 AM, xie...@chinatelecom.cn wrote:
