# Inputs:
#   $1 - ssh user to use to connect to Mikrotik (usualy "admin")
#   $2 - Mikrotik address
#
# The address can be:
#  - Previously configured IP address
#  - Default address: 192.168.88.1
#  - Local link IPv6 address

# How to find router's local link IPv6 address:
#   ping -6 fe80::%n
#
# Where n is the number of the interface where the router can be found as reported by "ip link":
#
# Example:
# $ ip link
# 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
#     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
# 3: enx207bd2dc0ebe: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
#     link/ether 20:7b:d2:dc:0e:be brd ff:ff:ff:ff:ff:ff
