99 Framed-IPv6-
Route
Routing information (IPv6 managed route) to be configured on the NAS for
a v6 WAN host (IPoE or PPPoE) that operates as a router. The
functionality is comparable with offering multiple PD prefixes for a single
host. The route included in the Framed-IPv6-Route attribute is accepted
as a managed route only if its next hop is a WAN host (DHCPv6 IA-NA,
SLAAC, or /128 data-triggered). As a consequence, Framed-IPv6-Routes
with an explicitly configured gateway prefix of a pd-host (DHCPv6 IA-PD)
will not be installed. A Framed-Route attribute is also ignored if the SAP
does not have anti-spoof configured to nh-mac (the host will be installed
as a standalone host without managed route). Any routes above the
configured limits are silently ignored. Optionally, a metric, tag, or protocol
preference can be specified for the managed route. If the metrics are not
specified, specified in a wrong format, or specified with out-of-range
values then default values are used for all metrics: metric=0, no tag and
preference=0. If an identical managed route is associated with different
routed subscriber hosts in the context of the same IES/VPRN service, up
to max-ecmp-routes managed routes are installed in the routing table
(configured as ecmp max-ecmp-routes in the routing instance).
Candidate ECMP Framed-IPv6-Routes have an identical prefix, equal
lowest preference, and equal lowest metric. “lowest ip next-hop” is the tie
breaker if more candidate ECMP Framed-IPv6-Routes are available than
the configured max-ecmp-routes. Other identical managed routes are
shadowed (not installed in the routing table) and an event is logged. Valid
RADIUS learned managed routes can be included in RADIUS accounting
messages with the 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).
100 Framed-IPv6-
Pool
The name of an assigned pool that should be used to assign an IPv6
address via DHCPv6 (IA-NA) to the WAN side of the user (IPoE, PPPoE).
Maps to DHCPv6 vendor-option [17], sub-option [1] wan-pool. Framed-
IPv6-Pool names longer than the allowed maximum are treated as host
setup failures. This attribute is an alternative to [97] Framed-IPv6-Prefix
and [26-6527-99] Alc-IPv6-Address, that also assigns IPv6 addressing to
the wan-side of a host via SLAAC or DHCPv6 IA-NA.
