No, but they do however work just great as an active-active pair of routers when cross linked and iBGP peered to each other and everything downstream connected to each one. Chris On Mon, Aug 21, 2023 at 9:43 AM Pascal Masha wrote: > Hello, > > Does the MX204 support virtual chassis setup? > >

*facepalm* You asked for a cost-free, publicly visible and available tool. The lack of such does *not* mean tools don't exist. It just means you won't find them available for free to the general public. Asking if X exists and being told 'no' does not say anything about whether Y exists or not.

I agree with the yang approach. I would probably convert to using Yang and download the yang files for whatever code version you are running. For every code version you can download the yang files. Then you have a choice to decide, either right a yang to yacc conversion tool or find one, or think
