Default command level
2: System level
Parameters
aging-time: Aging time for tunnel entries, in the range of 1 to 86400, in seconds.
Usage guidelines
This command is available only for tunnel interfaces operating in P2MP GRE tunnel mode.
If a device at the headquarters does not receive any packet from a branch before the aging time expires,
it removes the corresponding tunnel entry.
Too short a tunnel entry aging time may make tunnel entries age out too quickly, resulting in forwarding
failures of packets to the branch. Too long a tunnel entry aging time, on the other hand, may not be able
to make sure that the tunnel entry table gets updated in time. Set the aging time properly as required.
