DENOG MeetUp 2025-01 / Frankfurt

jnprsr ('ʤunəpɑrsər) is a small open source project that implements a parser for Juniper configuration files. The tool can be used to generate an AST (Abstract Syntax Tree) from a Juniper config file, which can then be processed further. Offbox config merge, pretty printing and sub-tree selection have been implemented so far.

I would like to present the beta version, briefly report on the development challenges and give an outlook on what else could be done with jnprsr.

We have encoded arbitrary data in SRv6 headers and transmitted them over the public internet. Our talk presents our findings and gives further insights into SRv6 transparency across public networks.
