This document discusses two options for configuring SID for additional IGP algorithms such as SPF based on delay, MRT blue/red for Fast ReRoute...
At first, the handling of additional IGP algorithms may be seen as a second priority for the SPRING WG. However, this discussion may impact IGP encodings discussed in the OSPF and IS-IS WG. Such IGP extensions have been discussed for some time, with multiple interoperable implementations and expected deployments in the near future. Hence if change is needed, the more we wait, probably the harder.

We feel that starting the discussion on the mailing list now would be better than waiting for Pragues.

So we'd like to encourage the WG to read this document and comment it on the mailing list.

Bruno, John

> Abstract:
>    Segment routing uses globally-known labels to accomplish destination-
>    based forwarding along shortest paths computed using Dijkstra's
>    algorithm with IGP metrics.  This draft discusses how to use segment
>    routing to accomplish destination-based forwarding along paths
>    computed using other algorithms and metrics.  In particular, the
>    draft contrasts two different options for associating labels with
>    different algorithms for computing forwarding next-hops.
> 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.
