Table ID option in SBR Meta Plugin #1046

Closed LionelJouin closed 2 weeks ago

LionelJouin commented 4 months ago

This is a follow-up to: https://github.com/containernetworking/cni/issues/1061

The route table ID can now be specified using the CNI Spec v1.1 and the Source Based Routing documentation mentions a potential enhancement to pass the table number as an input. https://www.cni.dev/plugins/current/meta/sbr/#future-enhancements-and-known-limitations

Here is the expected behavior with this change:

Using the option to set the table number in the SBR meta plugin, a policy route will be created for each IP added for the interface returned by the main plugin. Unlike the default behavior, the routes will not be moved to the table.
The default behavior (table ID not set) will be kept.

I would like to implement it, I will open a PR once https://github.com/containernetworking/plugins/pull/1021 gets merged.
