B) To request configuration information
C) To inform other devices of their presence and capabilities
D) To establish a direct connection with hosts

Answer 1

IPv6 routers send unsolicited router advertisements to inform other devices of their presence and capabilities, and to provide configuration information.

Step-by-step explanation:

IPv6 routers send unsolicited router advertisements to inform other devices of their presence and capabilities. When a new device joins the network, it may not know about the existence of a router. By sending the router advertisements, routers actively broadcast their presence, informing the devices about their availability for communication.

Router advertisements also help devices learn about the available network configurations. Devices can use the information in the advertisements to autonomously configure their network settings, such as obtaining an IPv6 address or determining the default gateway.

Additionally, the router advertisements include other important information, such as the lifetime of the advertised router, allowing devices to update their routing tables accordingly.
