The ntp-service manycast-server command configures the manycast server mode.
The undo ntp-service manycast-server command cancels configuring the NTP manycast server mode.
By default, the manycast server service is not configured.
ntp-service manycast-server [ ip-address | ipv6 [ ipv6-address ] ]
undo ntp-service manycast-server [ ip-address | ipv6 [ ipv6-address ] ]
| Parameter | Description | Value |
|---|---|---|
ip-address |
Specifies the manycast IPv4 address, which is a Class D address. |
By default, it is 10.0.1.1. |
ipv6 ipv6-address |
Specifies the manycast IPv6 address. |
By default, it is FF0E::0101. |

The manycast server responds to manycast client packets. Based on the response, manycast client creates ephemeral association and work in client server mode.
If you configure manycast server on the current interface, it is ready to receive NTP manycast messages and the local device runs in the server mode.
If you execute undo ntp-service manycast-server command and multicast IP address is not specified then local device searches for default IP addresses. The multicast server with default IP address is 10.0.1.1 in IPv4 network and FFOE::101 in IPv6 address. If the local device finds the default IP address, this command cancels the manycast server configuration, else it does not perform any action.
