Hi all,

It is about the task 5.2

        --------R1-------
           | | |
           | | |
           | | |
 R5 ---| | R3
           | | |
           | | |
           | | |
         --------R2-------

R1 - R2 - R3 - running OSPF

R1 - R2 - R3 - running EIGRP

R1 - R2 - mutual redistribution (same metric in both routers)

Loopback's from R1 and R2 in OSPF

Then, R5 has two EIGRP entries for 150.1.1.1

Rack1R5#sh ip route 150.1.1.1
Routing entry for 150.1.1.0/24
  Known via "eigrp 10", distance 170, metric 281856, type external
  Redistributing via eigrp 10, rip
  Advertised by rip metric 5
  Last update from 152.1.125.2 on Ethernet0/0, 00:13:50 ago
  Routing Descriptor Blocks:
  * 152.1.125.2, from 152.1.125.2, 00:13:50 ago, via Ethernet0/0
      Route metric is 281856, traffic share count is 1
      Total delay is 1010 microseconds, minimum bandwidth is 10000 Kbit
      Reliability 255/255, minimum MTU 1500 bytes
      Loading 1/255, Hops 1
    152.1.125.1, from 152.1.125.1, 00:13:50 ago, via Ethernet0/0
      Route metric is 281856, traffic share count is 1
      Total delay is 1010 microseconds, minimum bandwidth is 10000 Kbit
      Reliability 255/255, minimum MTU 1500 bytes
      Loading 1/255, Hops 1

R5 is in BGP 100

R1 and R2 in BGP 200

The question ask to R5 routes through R1 using MED.

So, BGP table in R5 shows:

*> 222.22.2.0 150.1.1.1 200 0 200 254 ?
* 150.1.2.2 250 0 200 254
?

That is correct and I could stop here.

But R5 know 150.1.1.1 via R1 and R2 !!!!

So, when trace from R4 (inside AS100) sometimes this:

Rack1R4#traceroute 222.22.2.0

Type escape sequence to abort.
Tracing the route to 222.22.2.0

  1 152.1.45.5 44 msec 40 msec 40 msec
  2 152.1.125.1 40 msec 40 msec 32 msec <<<<<
  3 152.1.123.3 72 msec 80 msec 80 msec
  4 152.1.37.7 80 msec 80 msec 80 msec
  5 *

and this:

Rack1R4#traceroute 222.22.2.0

Type escape sequence to abort.
Tracing the route to 222.22.2.0

  1 152.1.45.5 44 msec 40 msec 40 msec
  2 152.1.125.2 40 msec 40 msec 40 msec <<<<<<
  3 152.1.123.3 80 msec 80 msec 92 msec
  4 152.1.37.7 68 msec 80 msec 80 msec
  5 *

So, my question is: Will I receive these points ? Is there any problem with
the IGP configuration ?

In R5 I have the following message on "debug ip routing":
*Nov 6 22:42:24.699: is_up: 0 state: 4 sub state: 1 line: 0 has_route:
False
What it means ?

Thanks for any help.

Regards,

Danilo
