Extract to json file the "show bgp ipv4 unicast json detail"

[pedroaston]

I started today with FRRouting so bear in mind my lack of knowledge 😅

Context

I implemented a BGP peer in order to receive an ISP's BGP full-routing table (880k routes). I would like to use FRRouting to manipulate the BGP table information to track communities, as-paths and other details. I see that with the command "show bgp ipv4 unicast json detail" it's generated a json file with all the information I need. With this json I could then parse it with some python scripts and and extract relevant details.

Some of the use-cases are:

• validating community marking.
• build a database to create a more detailed looking glass.

Question

I don't know if there is a way to fetch this information on the FRRouting filesystem, because logging the vtysh with all those routes its not practical and hard to automate. Is there a way for me to get that info in json fast?

Thanks 😄
