Configuring the aging time for dynamic path MTUs
After the path MTU from a source host to a destination host is dynamically determined (see "IPv6 path MTU discovery"), the source host sends subsequent packets to the destination host based on this MTU. After the aging time expires, the dynamic path MTU is removed and the source host re-determines a dynamic path MTU through the path MTU mechanism.
The aging time is invalid for a static path MTU.
To configure the aging time for dynamic path MTUs:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Configure the aging time for dynamic path MTUs. | ipv6 pathmtu age age-time | Optional. 10 minutes by default. |
