83 Tunnel-Preference Indicates the relative preference assigned to each tunnel if
more than one set of tunneling attributes is returned by the
RADIUS server to the tunnel initiator. 0x0 (zero) being the
lowest and 0x0FFFFFF(16777215) being the highest numerical
value. The tunnel having the numerically lowest value in the
Value field of this Attribute is given the highest preference.
Other tunnel selection criteria are used if preference values
from different tunnels are equal. Preference 50 is used when
attribute is omitted. Values above the Limits wrap around by
Freeradius before send to the NAS (start again from zero until
the Limits).
90 Tunnel-Client-Auth-ID Used during the authentication phase of tunnel establishment
and copied by the LAC in L2TP SCCRQ AVP 7 Host Name.
Reported in L2TP Tunnel/Link accounting when length is
different from zero. The value with tag 0 is used as default for
the tunnels where the value is not specified. Preconfigured
values are used when the attribute is omitted (configure
router/service vprn service-id l2tp local-name). The Node
system-name is copied in AVP Host Name if this attribute is
omitted and no local-name is configured.
91 Tunnel-Server-Auth-ID Used during the authentication phase of tunnel establishment
and reported in L2TP Tunnel/Link accounting when length is
different from zero. For authentication the value of this attribute
is compared with the value of AVP 7 Host Name from the
received LNS SCCRP. Authentication from LAC point of view
passes if both attributes are the same. This authentication
check is not performed if the RADIUS attribute is omitted.

as attribute 26-6527-48 Alc-Tunnel-Max-Sessions:0. No
sessions are setup above the Limits. Preconfigured values
(configure router/service vprn service-id l2tp session-limit)
are used when attribute is omitted.
