in reply to SSH connection to 100 routers
"...I cant manually connect to 900 servers to establish the SSH key..."
Probably you can delegate this to a script. What about something like this: sshpass -f secrets.file ssh-copy-id user@host?
I don't remember the exact syntax. Please see sshpass and ssh-copy-id for details.
Best regards, Karl
