# Routinator Configuration
#
# The configuration file is a TOML file. It consists of a sequence of
# key-value pairs, each on its own line. Strings are to be enclosed in
# double quotes. Lists of values can be given by enclosing a
# comma-separated sequence of these values in square brackets.
#
# See https://github.com/toml-lang/toml for detailed information on the
# format.
#
# This file contains all configuration settings with explanations and their
# default values.

# Repository directory
#
# This is where Routinator stores the local copy of the RPKI repository.
# Any relative path is interpreted with respect to the directory this config
# lives in.
#
# This setting is mandatory.
#
repository-dir = "/home/routinator/.rpki-cache/repository/"

# Trust Anchor Locator (TAL) directory
#
# All the files with the extension ".tal" in this directory are treated as
# trust anchor locators for RPKI validation.
#
# A relative path is interpreted with respect to the directory this config
# lives in.
#
# This setting is mandatory.
#
tal-dir = "/home/routinator/.rpki-cache/tals/"

# Local exceptions files
#
# This settings contains a array of paths to files that contain local
# exceptions. The files are JSON files according to RFC 8416 (aka SLURM).

# Strict mode
#
# If strict mode, Routinator will stick to the requirements in the respective
# RFCs very strictly. See
# https://github.com/NLnetLabs/rpki-rs/blob/master/doc/relaxed-validation.md
# for information on what is allowed when strict mode is off.

# This is a list of arguments to give to rsync.

# Number of parallel rsync commands
#
# This is the maximum number of rsync commands that are run in parallel.
# We are not sure, if the current default is any good. Some feedback whether
# it is causing trouble or whether a higher value would even be fine is very
# much appreciated.

#rsync-count = 4

# Number of validation threads
#
# The number of threads that are used for validating the repository. The
# default value is the number of CPUs.
validation-threads = 2

# Refresh interval
#
# How often the repository should be updated and validated in RTR mode.
# Specifically, this is the number of seconds the process will wait after
# having finished validation before starting the next update.
#
# The default is the value indirectly recommended by RFC 8210.
refresh = 3600

# RTR retry interval
#
# This is the time an RTR client is told to wait before retrying a failed
# query in seconds.

# This is the time an RTR client is told to keep using data if it can't
# refresh it.

#
# The number of deltas to keep. If a client requests an older delta, it is
# served the entire set again.

# This is an array of strings, each string a socket address of the form
# "address:port" with IPv6 address in square brackets.

# which to log messages.

# Can also be "default", in which case "syslog" is used in daemon mode and
# "stderr" otherwise

# Syslog facility
#
# The syslog facility to log to if syslog logging is used.

# relative, it is relative to the directory this config file lives in.

# no pid file is used.
