Too short a tunnel entry aging time may make tunnel entries get aged 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.
Examples
# Set the P2MP tunnel entry aging time to 10 seconds.
<Sysname> system-view
