Hi Amr,
Your RADIUS server is located upstream from the E120 right? Ie. It is
not an access-internal route but rather it is reachable via another
protocol such as BGP, static, or OSPF. Adjusting protocol preferences
is less than ideal and you should avoid this in almost all designs.
Why do you say that the performance of the E120 is affected by the
default route that is assigned to a user?
You can issue 'radius ignore <attribute>' commands to ignore specific
RADIUS messages that are included in the access-accept. I would not
just fix the problem here if the issue is really a mistake in a RADIUS
profile upstream; that would be the best place to fix the issue.

Dear All,
I have a problem in my E120 Router , where i have
configured the
RADIUS Server to send to the Users on the E120 thier IP Subnet so
that the
IP subnets of the users will be "Access-internal" routes as below
E120#sh ip route 10.10.10.10
Protocol/Route type codes:
I1- ISIS level 1, I2- ISIS level2,
I- route type intra, IA- route type inter, E- route type external,
i- metric type internal, e- metric type external,
P- periodic download, O- OSPF, E1- external type 1, E2- external
type2,
N1- NSSA external type1, N2- NSSA external type2
L- MPLS label, V- VRF, *- via indirect next-hop
Prefix/Length Type Next Hop Dst/Met
Interface
------------------ --------- --------------- ----------
-----------------------
10.10.10.10/32 *AccIntern *0.0.0.0 2/0
GigabitEthernet3/0/0.505252.59
but by mistake someone configured the RADIUS to send the default route
(0.0.0.0.0/0) for a specific user which affects the performance of
the E120
router and modifyed the current default route learned by OSPF
So the Question is
Is it possible to restrict the routes the comes from the RADIUS
Server and
not accepting it all (e.g denying the default route from the radius) ?
or
Is it possible to modify the admin distance for the Access-internal
routes
so that it will be higher that the dynamic default route configured
on the
E120 router ?
Appreciate your help
Thanks In Advance
Regards
Amr
