EIGRP problem. I can´t install a static route into eigrp topology table

Hi all,

I have a problem to insert into EIGRP a per-user static route via RADIUS.

When RADIUS send av-pair to router the router install routes into routing table but, and this is my problem, EIGRP dont install into topology table only in certain case.

I can see that.

sh ip route static
U [1/0] via
U [1/0] via

both routes are assigned via user in RADIUS

userpp        Auth-Type := local, User-Password == "pass"
                Framed-IP-Address =,
                cisco-avpair += "ip:route#1=",
                cisco-avpair += "ip:route#2=",
                Service-Type = Framed-User,
                Framed-Protocol = PPP

but only the route that his nexthop is different to the user IP works.

sh ip eigrp topolo
IP-EIGRP (AS 10): Topology entry for
  State is Passive, Query origin flag is 1, 1 Successor(s), FD is 2816
  Routing Descriptor Blocks:, from Rstatic, Send flag is 0x0
      Composite metric is (2816/0), Route is External
      Vector metric:
        Minimum bandwidth is 1000000 Kbit
        Total delay is 10 microseconds
        Reliability is 255/255
        Load is 15/255
        Minimum MTU is 1500
        Hop count is 0
      External data:
        Originating router is (this system)
        AS number of route is 0
        External protocol is Static, external metric is 0
        Administrator tag is 0 (0x00000000)

sh ip eigrp topology
% IP-EIGRP (AS 10): Route not in topology table

I am using IOS c7200-adventerprisek9-mz.124-24.T1.bin

But the same configuration (at least I think that) works well for both routes in other router

Somebody can help me?

thanks in advance.

I found the solution.

I don´t know why but in this case EIGRP can't take the metric for static routes automatically. So as, i set into redistribution route the set metric command and the route start to appear into EIGRP topology table.

Somebody know some debug where i could see this behavior?

Hello David,

now that I see it, it is a reasonable solution and you have been kind to provide feedback

about debug commands

may be the FSM debug may be of help

debug ip eigrp ?
  <1-65535>      AS number
  <1-65535>      Autonomous System
  neighbor       IP-EIGRP neighbor debugging
  notifications  IP-EIGRP event notifications
  summary        IP-EIGRP summary route processing
  vrf            Select a VPN Routing/Forwarding instance

debug eigrp ? 
  fsm        EIGRP Dual Finite State Machine events/actions
  neighbors  EIGRP neighbors
  nsf        EIGRP Non-Stop Forwarding events/actions
  packets    EIGRP packets
  transmit   EIGRP transmission events

note that there are two series of debug commands one with ip keyword and one without

Hope to help

Thank you Giuseppe,

I will try "debug eigrp fsm". I am sure that DUAL is the responsable for that.

I did try different debugs, including some "debug eigrp" but for some reason i didn't view fsm...
