Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
It is recommended that the tunnel source is identified using the interface ID and not the IP address. Using the
interface ID enables the router to mark the tunnel as down when the interface is down and the routing protocol
tries to find and use an alternate route to the tunnel route.
