Switch(Config-if-Vlan1)#ipv6 nd max-ra-interval 20

12.2.14 ipv6 nd prefix

Command:

ipv6 nd prefix <ipv6-prefix | prefix-length>{ [<valid-lifetime> <preferred-lifetime>]

[ no-autoconfig | off-link[no-autoconfig] ]}

Function:

Configure the address prefix and relative parameters for router announcement.

<prefix-length> is the length of the address prefix of the specified announcement,

<valid-lifetime> is the valid lifetime of the prefix,

<preferred-lifetime> is the preferred lifetime of the prefix, and the valid lifetime must be no smaller

than preferred lifetime.

no-autoconfig says this prefix can not be used to automatically configure IPv6 address on the host
