5.4.7 Configuring Other Information to Be Advertised
A router advertisement message carries information such as the maximum number of hops,
prefix option, neighbor hold time, and keepalive time.
Context
Duplicate Address Detect (DAD) is a process of IPv6 automatic address configuration. You can
configure the number of DAD messages which are sent continuously.
Set the interval of sending Neighbor Solicitation (NS) messages on the device. By default, NS
re-transmitting time interval is 1000ms.
Neighbor Unreachability Detection (NUD) checks the reachability of neighbors. By default,
NUD value is 30000ms.
The MTU of the interface determines whether to fragment IP packets on the interface. Default
MTUs vary with interface types. The MTU on an GigabitEthernet interface defaults to be 1500
bytes.
