Situation
在 IPv6 網路環境中,Router Advertisement(RA)是由路由器透過 ICMPv6 封包主動傳送給區域網路中其他裝置的重要機制,用於協助終端節點自動獲取 IPv6 位址與相關網路參數。
RA 是 Stateless Address Autoconfiguration(SLAAC)的基礎,讓終端裝置在無需手動設定或 DHCPv6 伺服器的情況下,即可建立通訊能力。
Configuration
# Enabled by default on ZYXEL.
[1]
System > IPv6 Neighbor Discovery > IPv6 Router Discovery Setup page.

Select and edit the interface and Look for the option labeled "Suppress".

Suppress on = disable sending out RA packet in the network.
Check
Using PC connect to the network and check if you are receiving ipv6 address or not.
