And start asking for correct solution a) policy api (e.g. gRPC call, where reply gives actions) - could be your program running on the router itself, not necessarily centralised server b) mruby or lua instead of vendor DSL for policy evaluation - ideally something >1 vendor will implement So that the built-in DSL is for simple/naive cases, and operators who need to implement complex policies across multiple vendors have much simpler time doing that. -- ++ytti _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
