Parameters
vpn-instance vpn-instance-name: Specifies the VPN instance to which the specified address belongs. The
vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. The specified VPN instance
must already exist. If the specified IPv6 address is on the public network, do not use this option.
ipv6-address: Specifies an IPv6 address.
Usage guidelines
It is a good practice to specify the IPv6 address of the loopback interface as the source IPv6 address for
outgoing ping echo request and ICMPv6 error messages. This feature helps users to locate the sending
device easily.
Examples
# Specify IPv6 address 1::1 as the source address for outgoing ICMPv6 packets.
<Sysname> system-view
[Sysname] ipv6 icmpv6 source 1::1
ipv6 nd autoconfig managed-address-flag
Use ipv6 nd autoconfig managed-address-flag to set the managed address configuration (M) flag to 1
so that the host can obtain an IPv6 address through stateful autoconfiguration (for example, from a
DHCPv6 server).
Use undo ipv6 nd autoconfig managed-address-flag to restore the default.
Syntax
ipv6 nd autoconfig managed-address-flag
undo ipv6 nd autoconfig managed-address-flag
Default
The M flag is set to 0 so that the host can obtain an IPv6 address through stateless autoconfiguration.
