Setting the aging time for dynamic path MTUs
After the device dynamically finds the path MTU to a destination host (see "IPv6 path MTU discovery"), it performs the following operations:
Sends packets to the destination host based on the path MTU.
Starts the aging timer.
When the aging timer expires, the device removes the dynamic path MTU and finds the path MTU again.
To set the aging time for dynamic path MTUs:
