User Guidelines
The router advertises its global IPv6 prefixes in its router advertisements (RAs). An RA only
includes the prefixes of the IPv6 addresses configured on the interface where the RA is
transmitted. Addresses are configured using the ipv6 address interface configuration command.
Each prefix advertisement includes information about the prefix, such as its lifetime values and
whether hosts should use the prefix for on-link determination or address auto-configuration.
Use the ipv6 nd prefix command to configure these values.
The ipv6 nd prefix command will allow you to preconfigure RA prefix values before you
configure the associated interface address. In order for the prefix to be included in RAs, you
must configure an address that matches the prefix using the ipv6 address command. Prefixes
specified using ipv6 nd prefix without an associated interface address will not be included in
RAs and will not be committed to the device configuration.
Example
The following example sets the IPv6 prefixes to include in the router advertisement.
console(config)#interface vlan 11
console(config-if-vlan11)#ipv6 nd prefix 2020:1::1/64
ipv6 nd ra-interval
Use the ipv6 nd ra-interval command in Interface Configuration mode to set the transmission
interval between router advertisements.
