Usage guidelines

The M flag in RA advertisements determines whether receiving hosts use stateful autoconfiguration to obtain IPv6 addresses.

• If the M flag is set to 1 in RA advertisements, receiving hosts use stateful autoconfiguration (for example, from an DHCPv6 server) to obtain IPv6 addresses.

• If the M flag is set to 0 in RA advertisements, receiving hosts use stateless autoconfiguration. Stateless autoconfiguration generates IPv6 addresses according to link-layer addresses and the prefix information in the RA advertisements.

Examples

# Set the M flag to 1 in RA advertisements to be sent.
