eigrp topology question

Mike Schooley

Level 1

this is the output for sho ip route 10.35.29.0.    Notice the distance is 90, and they type is internal

Routing entry for 10.35.29.0/24
  Known via "eigrp 136", distance 90, metric 28674560, type internal
  Redistributing via eigrp 136
  Last update from 10.55.3.1 on Tunnel4, 4d00h ago
  Routing Descriptor Blocks:
  * 10.55.3.1, from 10.55.3.1, 4d00h ago, via Tunnel4
      Route metric is 28674560, traffic share count is 1
      Total delay is 1100100 microseconds, minimum bandwidth is 5000 Kbit
      Reliability 255/255, minimum MTU 1400 bytes
      Loading 6/255, Hops 2

This is the output for sho ip eigrp top 10.35.29.0/24  notice that both routes including the one to T4 are external, there are no internal routes in this topology output, so how is it that the route in my routing table is an eigrp internal route see next line,  am I missing something, i feel like I should know this.  I think that the route in the routing table should be to T0.  Out of about 200 routes, only about 10 are like this, trying to figure out why.

I am not sure what is going on. But here is what I observe. When you did the show ip route there was an entry in the routing table and so it's EIGRP state would be passive. When you did the shoe topology the EIGRP state is active. So what changed between the commands?
