Parameters
server-name
: Specifies an NTP server by its host name, a case-insensitive string of 1 to 253
characters.
ipv6-address
: Specifies an NTP server by its IPv6 address.
vpn-instance vpn-instance-name
: Specifies MPLS L3VPN instance to which the NTP
server belongs. The
vpn-instance-name
argument is a case-sensitive string of 1 to 31
characters. If the NTP server 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 NTP server. The value range for the
keyid
argument is 1 to 4294967295. If you do not specify
this option, the local device and NTP server do not authenticate each other.
source
interface-type interface-number
: Specifies the source interface for IPv6 NTP
messages. If the specified IPv6 NTP server address is not a link local address, the source IPv6
address for IPv6 NTP messages sent by the local device to the NTP server is the IPv6 address of the
specified source interface. If the specified IPv6 NTP server 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-number
argument represents 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
.
Usage guidelines
When you specify an IPv6 NTP server for the device, the device is synchronized to the NTP server,
but the NTP server is not synchronized to the device.
To synchronize the PE to a PE or CE in a VPN instance, provide the
vpn-instance
vpn-instance-name
option in your command.
