ipv6 nd other-cong-ag

ipv6 nd other-config-flag
Parameters None
Defaults Not congured
Command Mode INTERFACE
Usage Information The no version of this command disables the other-config-flag option in RA messages.

ipv6 nd prex
Congures the IPv6 prexes that are included in messages to neighboring IPv6 routers.
Syntax
ipv6 nd prefix {ipv6-prefix | default} [no-advertise] [no autoconfig] [no-rtr-
address] [off-link] [lifetime {valid-lifetime seconds | infinite} {preferred-
lifetime seconds | infinite}]
Parameters
• ipv6-prefix — Enter an IPv6 prex in x:x::y/mask format to include the prex in RA mesages. Include
prexes that are not already in the subnets on the interface.
• default — Congure the prex parameters advertised in all subnets congured on the interface.
• no-advertise — (Optional) Do not advertise the specied prex. By default, all prexes in congured
subnets advertise.
•
no-autoconfig — (Optional) Sets AdvAutonomous to Off for the specied prex in the radvd.conf le.
This setting tells hosts to not use this prex for address autoconguration. By default, AdvAutonomous is On.
