mikrotik scripting

hello team
i have 4 router
router A 10.1.1.1 user admin pass admin
router B 10.1.1.2 user admin pass admin
router C 10.1.1.3 user admin pass admin
router D 10.1.1.4 user admin pass admin

can anyone help me to write a script in router A

to enter ssh in router B C D and run other local script
thank you

What is your goal by making the routers talk to each other?

i have one main router connected to 15 router pppoe servers
every pppoe server have a queue tree more than 60 pcq queues
a scheduler task run to reduce the pcq queues in each router
sometimes i have to do it manually
i need one script in the main router to enter ssh to router A than run script “test1”
enter ssh to router B than run script “test2”
enter ssh to router C than run script “test3”
