If you have specified the source interface for IPv6 NTP messages in the
ntp-service ipv6
unicast-server
or
ntp-service ipv5 unicast-peer
command, the interface specified in the
ntp-service ipv6 unicast-server
or
ntp-service ipv6 unicast-peer
command works as the
source interface for IPv6 NTP messages. If you have configured the
ntp-service ipv6
broadcast-server
or
ntp-service
ipv6
multicast-server
command, the source interface for
the broadcast or multicast NTP messages is the interface configured with the respective
command.
•
If the specified source interface is down, the device does not send IPv6 NTP messages.
Examples
# Specify the source interface of IPv6 NTP messages as VLAN-interface 1.
<Sysname> system-view
[Sysname] ntp-service ipv6 source vlan-interface 1
ntp-service ipv6 unicast-peer
Use
ntp-service
ipv6
unicast-peer
to specify an IPv6 symmetric-passive peer for the device.
Use
undo ntp-service
ipv6
unicast-peer
to remove the IPv6 symmetric-passive peer specified for
the device.

Parameters
peer-name
: Specifies the host name of the symmetric-passive peer, a case-insensitive string of 1 to
253 characters.
ipv6-address
: Specifies the IPv6 address of the symmetric-passive peer. It must be a unicast
address, rather than a multicast address.
vpn-instance
vpn-instance-name
: Specifies the MPLS L3VPN to which the symmetric-passive peer
belongs, where
vpn-instance-name
is a case-sensitive string of 1 to 31 characters. If the
symmetric-passive peer is on the public network, do not specify this option.
authentication-keyid
keyid
: Specifies the key ID to be used for sending NTP messages to the peer,
where
keyid
is in the range of 1 to 4294967295. If this option is not specified, the local device and the
peer do not authenticate each other.
priority
: Specifies the peer specified by
ip-address
or
peer-name
as the first choice under the same
condition.
source
interface-type interface-number
: Specifies the source interface for IPv6 NTP messages. If
the specified passive peer address is not a link local address, the source IPv6 address for IPv6 NTP
messages sent by the local device is the IPv6 address of the specified source interface. If the
