R0106-HP MSR Router Series Layer 3 - IP Services Command Reference(V7)

288
Usage guidelines
After the path MTU from a source host to a destination host is dynamically determined, 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.
• The source host re-determines a dynamic path MTU through the Path MTU mechanism.
The aging time is invalid for a static Path MTU.
Examples
# Set the aging time for a dynamic Path MTU to 40 minutes.
<Sysname> system-view
[Sysname] ipv6 pathmtu age 40

display ipv6 pathmtu
ipv6 prefer temporary-address
Use ipv6 prefer temporary-address to enable the system to preferentially use the temporary IPv6 address
of the sending interface as the source address of a packet.
Use undo ipv6 prefer temporary-address to restore the default.
Syntax
ipv6 prefer temporary-address
undo ipv6 prefer temporary-address
Default
The system does not preferentially use the temporary IPv6 address of the sending interface as the source
address of a packet.
Views

Predefined user roles
network-admin
Usage guidelines
The temporary address function enables the system to generate and preferentially use the temporary IPv6
address of the sending interface as the source address of a packet. If the temporary IPv6 address cannot
be used because of a DAD conflict, the system uses the public IPv6 address.
Examples
# Enable the system to preferentially use the temporary IPv6 address of the sending interface as the
source address of the packet.

[Sysname] ipv6 prefer temporary-address
