frr using netconf datastores?
by Thomas.Swendseid＠gd-ms.com 05 Jan '23

05 Jan '23

Dear FRR Dev team, I had a question on whether the FRR in its current implementation works with Netconf and Yang? I do believe it does but I haven't been able to fully piece this together from the available documentation and other sources. I have downloaded the FRR (v 8.4.1), compiled it, and started it such that the ospfd is up and running. I've started netopeer2-server and netopeer2-cli and I can connect and see the datastores (running, candidate, startup) available. But my question is whether ospfd is consuming the 'startup' or 'running' datastore? The FRR was compiled with sysrepo enabled as well as specifying "-M sysrepo" on the ospfd command line. I'm not seeing any output from the daemon that would make me think it's using the datastore. Do I have to implement any callbacks or do any development work to have the ospfd use the datastore? Thanks for your help.
