becomes unnecessary, thus the problems and system cost caused by NAT deployment
are solved naturally.
Support extensively deployed Routing Protocol. IPv6 has kept and extended the
supports for existing Internal Gateway Protocols (IGP for short), and Exterior Gateway
Protocols (EGP for short). For example, IPv6 Routing Protocol such as RIPng, OSPFv3,
IS-ISv6 and MBGP4+, etc.
Multicast addresses increased and the support for multicast has enhanced. By
dealing with IPv4 broadcast functions such as Router Discovery and Router Query, IPv6
multicast has completely replaced IPv4 broadcast in the sense of function. Multicast not
only saves network bandwidth, but enhances network efficiency as well.
1.2.2 IP Configuration
Layer 3 interface can be configured as IPv4 interface, IPv6 interface.

1.2.2.2 IPv6 Address Configuration
The configuration Task List of IPv6 is as follows:
1. IPv6 basic configuration
(1) Configure interface IPv6 address
2. IPv6 Neighbor Discovery Configuration
(1) Configure DAD neighbor solicitation message number
(2) Configure send neighbor solicitation message interval
(3) Configure static IPv6 neighbor entries
