Defaults 1500 bytes
Command Mode INTERFACE
Usage Information The no version of this command restores the default MTU value advertised in RA messages.
Example
OS10(config)# interface ethernet 1/2/3
OS10(conf-if-eth1/2/3)# ipv6 nd mtu 2500
Supported Releases 10.4.0E(R1) or later
ipv6 nd other-cong-ag
Sends RA messages that tell hosts to use stateful autoconguration to obtain nonaddress-related information.
Syntax
ipv6 nd other-config-flag
Parameters None
Defaults Not congured
Command Mode INTERFACE
Usage Information The no version of this command disables the other-config-flag option in RA messages.
Example
OS10(config)# interface ethernet 1/2/3
OS10(conf-if-eth1/2/3)# ipv6 nd other-config-flag
Supported Releases 10.4.0E(R1) or later
ipv6 nd prex
Congures the IPv6 prexes that are included in Router Advertisement (RA) 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 prex in x:x::y/mask format to include the prex in RA mesages. Include
prexes that are not already in the subnets congured on the interface.
• default — Congure the prex parameters advertised in all subnets congured on the interface.
• no-advertise — (Optional) Do not advertise the specied prex. By default, all prexes in congured
subnets are advertised.
•
no-autoconfig — (Optional) Sets AdvAutonomous to Off for the specied prex in the radvd.conf le.
This setting tells hosts to not use this prex for address autoconguration. By default, AdvAutonomous is On.
• no-rtr-address — (Optional) Sets AdvRouterAddr to Off for the prex in the radvd.conf le. 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 prex in the radvd.conf le. The Off setting tells
hosts to not use this prex for on-link determination. By default, AdvOnLink is On.
• lifetime {valid-lifetime seconds | infinite} — (Optional) Sets AdvValidLifetime (in
seconds) for the prex in the radvd.conf le. The prex is valid for on-link determination only for the specied
lifetime. The default is 86400 seconds (1 day). The infinite setting allows the prex to be valid for on-link
determination with no time limit.
• lifetime {preferred-lifetime seconds | infinite} — (Optional) Sets
AdvPreferredLifetime (in seconds) for the prex in the radvd.conf le. IPv6 addresses generated from
the prex using stateless autoconguration remain preferred for the congured lifetime. The default is 14400
