ipv6 nd prefix
Configures the IPv6 prefixes 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 prefix in x:x::y/mask format to include the prefix in RA mesages. Include
prefixes that are not already in the subnets on the interface.
default — Configure the prefix parameters advertised in all subnets configured on the interface.
no-advertise — (Optional) Do not advertise the specified prefix. By default, all prefixes in configured
subnets advertise.
no-autoconfig — (Optional) Sets AdvAutonomous to Off for the specified prefix in the radvd.conf file.
This setting tells hosts to not use this prefix for address autoconfiguration. By default,
AdvAutonomous is
On.
no-rtr-address — (Optional) Sets AdvRouterAddr to Off for the prefix in the radvd.conf file. The
Off setting tells hosts to not use the advertising router's address for on-link determination. By default,
AdvRouterAddr is On.
off-link — (Optional) Sets AdvOnLink to Off for the prefix in the radvd.conf file. The Off setting tells
hosts to not use this prefix for on-link determination. By default, AdvOnLink is On.
lifetime {valid-lifetime seconds | infinite} — (Optional) Sets AdvValidLifetime in
seconds for the prefix in the radvd.conf file. The prefix is valid for on-link determination only for the specified
