Hey all
I was wondering how everybody else is handling the rollout of change plans. I see in general two approaches:
a) Define a dynamic device-groups within NA and run "simple" changes with only commands
b) Define a advanced script and have one change plan for all devices
In my current "to-do" I want to setup DNS in the context of the management-VRF. Now this management VRF can be different across the network so I have the option to either: dynamically get the management vrf from something I know is working and push the config in there or I create some dynamic groups within NA grouped by VRF and then just run a simple command.
While I prefer the dynamic script and started going down this road, this would probably lead to a rather complicated setup. Meaning we need other general Info from the device as well, so I would probably write a Perl module to handle some general things like gathering "basic" device-info. But then to load this dynamically based on Device-Type I would have some logic there as well... In the end I'll probably end up with a rather extensive setup.
On the one hand the option "A" is rather easy to handle for all the operators, but option "B" is just cleaner and in my view a lot more "future-proofed" to rollout other things as well...
