ipv6 nd ra other-config-flag

no ipv6 nd ra other-config-flag


Ignored unless the M-bit (above) is disabled in RAs. Controls the O-bit in RAs the router transmits on the current VLAN or tunnel.

The no form of the command turns off (disables) the setting for that command in RAs.


Enabling the O-bit while the M-bit is disabled directs hosts on the VLAN to acquire their ND configuration settings from a DHCPv6 server and their global unicast prefixes from the RA.


In the default configuration, both the M-bit and the O-bit are disabled, and a host receiving the RA must acquire its prefix and ND configuration from the RA itself and not from a DHCPv6 server.

Default for both settings: Disabled
