ntp-service ipv6 unicast-peer
Use ntp-serviceipv6unicast-peerto specify an IPv6 symmetric-passive peer for the device.
Use undo ntp-serviceipv6unicast-peerto remove the IPv6 symmetric-passive peer specified for
the device.

Parameters
peer-name: Specifies a symmetric-passive peer by its host name, a case-insensitive string of 1 to
253 characters.
ipv6-address: Specifies asymmetric-passive peer by its IPv6 address. It must be a unicast address,
rather than a multicast address.
vpn-instancevpn-instance-name: Specifies the VPN to which the symmetric-passive peer belongs.
Thevpn-instance-nameargument 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-keyidkeyid: Specifies the key ID to be used for sending NTP messages to the peer.
The value range for the keyidargument is 1 to 4294967295. If you do not specify this option, the local
device and the peer do not authenticate each other.
priority: Specifies the peer specified by ipv6-address or peer-name as the first choice under the
same condition.
sourceinterface-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
specified passive peer address is a link local address, the IPv6 NTP messages are sent from the
specified source interface, and the source address of the messages is the link local address of the
interface.The interface-type interface-numberargumentrepresents the interface type and number. If
you do not specify an interface, the device automatically selects the source IPv6 address of IPv6
NTP messages. For more information, see RFC 3484.
