RADIUS ATTRIBUTES REFERENCE GUIDE

Issue: 01 3HE 10793 AAAB TQZZA 01 13
22 Framed-Route Routing information (IPv4 managed route) to be configured on the NAS for
a host (DHCP, PPPOE, ARP, or data-triggered) that operates as a router
without NAT (routed subscriber host). The route included in the Framed-
Route attribute is accepted as a managed route only if its next-hop points
to the hosts ip-address, if the next-hop address equals 0.0.0.0, or if the
included route is a valid classful network, in which case the subnet-mask
is omitted. If neither is applicable, this specific framed-route attribute is
ignored and the host is instantiated without this specific managed route
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 a 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 the 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-Routes have identical prefix, equal lowest preference and equal
lowest metric. The “lowest ip next-hop” is the tie breaker if more candidate
ECMP Framed-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. An alternative to RADIUS managed
routes are managed routes via host dynamic BGP peering.
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-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).
25 Class Attribute sent by the RADIUS server to the NAS in an Access-Accept or
CoA and is sent unmodified by the NAS to the Accounting server as part
of the Accounting-Request packet. Strings with a length longer than the
defined Limits are accepted but truncated to this boundary.
