#
# This script will take a config file containing the Username and Password of the router, then using
# the ROS API, connect to the router and dump you a list of current BGP Sessions and tell you their
# status.  The output can then be used for any number of your own systems.
#
# For Mikrotik 7.10 and beyond, it'll finally show the prefix count of the peer!
