26-6527-200 Alc-v6-Preferred-
Lifetime
IPv6 address/prefix preferred lifetime is the length of time that a valid address/
prefix is preferred (i.e., the time until deprecation). When the preferred lifetime
expires, the address/prefix becomes deprecated (can still be used in existing
communications but should not be used as source in new communications).
This attribute is applicable only when an IPv6 address/prefix is assigned via
Radius (DHCPv6 proxy). Overrides the dhcp6 proxy-server preferred-lifetime
configuration on the group-interface.
The attribute value is expressed in seconds. Values outside the allowed range
(see limits) result in a setup failure.
If for the final determined values from the different sources (ludb, radius,
defaults), the following rule is violated:
renew timer <= rebind timer <= preferred lifetime <= valid lifetime
then the default timers are used: renew-timer = 30 min, rebind-timer = 48 min,
preferred-lifetime = 1hr, valid-lifetime = 1 day.
Note that only a single value can be specified that applies to both IA-NA
address and IA-PD prefix.
26-6527-201 Alc-v6-Valid-
Lifetime
IPv6 address/prefix valid lifetime is the length of time an address/prefix remains
in the valid state (i.e., the time until invalidation). When the valid lifetime
expires, the address/prefix becomes invalid and must no longer be used in
communications. Used as DHCPv6 lease time.
This attribute is applicable only when an IPv6 address/prefix is assigned via
Radius (DHCPv6 proxy). Overrides the dhcp6 proxy-server valid-lifetime
configuration on the group-interface.
The attribute value is expressed in seconds. Values outside the allowed range
(see limits) result in a setup failure.
If for the final determined values from the different sources (ludb, radius,
defaults), the following rule is violated:
renew timer <= rebind timer <= preferred lifetime <= valid lifetime
then the default timers are used: renew-timer = 30 min, rebind-timer = 48 min,
preferred-lifetime = 1hr, valid-lifetime = 1 day.
Note that only a single value can be specified that applies to both IA-NA
address and IA-PD prefix.
