ipv6-prefix/prefix-length to be configured via SLAAC (Router
Advertisement) to the WAN side of the user. Any non /64 prefix-length for
SLAAC host creation is treated as a session setup failure for this host. This
attribute is an alternative to [100] Framed-IPv6-Pool and [26-6527-99] Alc-
IPv6-Address, which assigns IPv6 addressing to the wan-side of a host via
DHCPv6 IA-NA. Attribute is also used in CoA and Disconnect Message (part
of the ESM or AA user identification-key). Attribute is omitted in accounting
via configure subscriber-mgmt radius-accounting-policy <name> include-
radius-attribute no framed-ipv6-prefix.
For Distributed Subscriber Management (DSM), if slaac is active for a UE,
the attribute contains the prefix assigned to this UE. Inclusion of this attribute
is enabled via configure aaa isa-radius-policy <policy-name> acct-include-
attributes framed-ipv6-prefix.
The routing information (IPv6 managed route) to be configured on the
NAS for a v6 wan-host (IPoE or PPPoE) that operates as a router.
Valid RADIUS learned managed routes can be included in RADIUS
accounting messages with following configuration: configure
subscriber-mgmt radius-accounting-policy <name> include-
radius-attribute framed-ipv6-route. Associated managed routes for
an instantiated routed subscriber host are included in RADIUS
accounting messages independent of the state of the managed route
(Installed, Shadowed or HostInactive). In case of a PPP session, when
a Framed-IPv6-Route is available while the corresponding routed
subscriber host is not yet instantiated, the managed route is in the state
"notYetInstalled" and will not be included in RADIUS accounting
messages.
Attribute that carries the Prefix (ipv6-prefix/prefix-length) to be delegated via
DHCPv6 (IA-PD) for the LAN side of the user (IPoE, PPPoE). Maps to
DHCPv6 option IA-PD [25] sub-option IA-Prefix [26] Prefix. An exact
Delegated-prefix-Length [DPL] match with configure service <service-id>
subscriber-interface <ip-int-name> ipv6 delegated-prefix-length [48..64] is
required with the received attribute prefix-length unless a variable DPL is
configured (configure service <service-id> subscriber-interface <ip-int-
name> ipv6 delegated-prefix-length variable).In the latter case we support
multiple hosts for the same group-interface having different prefix-length
[48..64] per host. Simultaneous returned attributes [123] Delegated-IPv6-
Prefix and [26-6527-131] Alc-Delegated-IPv6-Pool are handled as host setup
failures. Attribute is also used in CoA and Disconnect Message (part of the
ESM or AA user identification-key). Attribute is omitted in accounting via
configure subscriber-mgmt radius-accounting-policy <name> include-
radius-attribute no delegated-ipv6-prefix.
