IPv6 Routing Commands

Use the ipv6 nd prefix command to configure parameters associated with 

prefixes that the router advertises in its router advertisements. 

ipv6 nd prefix 

prefix/prefix-length [{valid-lifetime| infinite} {preferred-

lifetime| infinite}] [no-autoconfig] [off-link]
no ipv6 nd prefix prefix/

prefix-length

•

prefix — IPv6 prefix.

•

prefix-length — IPv6 prefix length.

•

valid-lifetime — Valid lifetime of the router in seconds. (Range: 

0–4294967295 seconds)

• infinite — Indicates lifetime value is infinite.
•

preferred-lifetime — Preferred-lifetime of the router in seconds. (Range: 

0–4294967295 seconds)

•

no-autocoding — Do not use Prefix for autoconfiguration.

•

off-link — Do not use Prefix for onlink determination.

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.
