IPv6 Routing Commands

604800 seconds is the default value for valid-lifetime, 2592000 seconds for 

preferred lifetime.

Interface Configuration (VLAN, Tunnel, Loopback) mode

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.

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

Use the ipv6 nd ra-interval command in Interface Configuration mode to set 

the transmission interval between router advertisements.
