Hi team, After switching to a backup RSP board (on ASR903), using the backup forced switching method, it became impossible to connect to the router via the ssh protocol (telnet worked, ping went through, and all protocols functioned). After returning to the main RSP board, the connection was possible again. Added error log. Please help solve problems.
