ipv6 nd ra managed-config-flag


ipv6 nd ra managed-config-flag

no ipv6 nd ra managed-config-flag


Controls the M-bit setting in RAs the router transmits on the current VLAN. Enabling the M-bit directs clients to acquire their IPv6 addressing and ND host configuration information for the current VLAN or tunnel interface from a DHCPv6 server.


  • When the M-bit is enabled, receiving hosts ignore the other-config-flag (O-bit) setting described below.

  • When the M-bit is disabled (the default), receiving hosts expect to receive their IPv6 addressing and ND configuration settings from the RA unless the O-bit is enabled.

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