IPSec Service modules support interfaces associated with secure IP tunnels. You configure and delete these interfaces statically; however, the router assigns tunnels to the interfaces dynamically. This mechanism means that you must manage the interfaces for tunnels manually; however, the router will add and remove tunnels when required.
For information about configuring secure IP interfaces, see JUNOSe IP Services Configuration Guide . For information about managing IPSec service interfaces, see JUNOSe Physical Layer Configuration Guide.
