4000 Router Series Layer 3 - IP Services Command Reference

Usage guidelines

The temporary address function enables the system to generate and preferably 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 preferably use the temporary IPv6 address of the sending interface as the source

address of the packet.

<Sysname> system-view

[Sysname] ipv6 prefer temporary-address

Usage guidelines

The default gateway sends an ICMPv6 redirect message to the source of an IPv6 packet to inform of a

better first hop.

Sending ICMPv6 redirect messages enables hosts that hold few routes to establish routing tables and find

the best route. Because this function adds host route into the routing tables, host performance degrades

when there are too many host routes. As a result, sending ICMPv6 redirect messages is disabled by

default.

Examples

# Enable sending ICMPv6 redirect messages.

<Sysname> system-view

[Sysname] ipv6 redirects enable
