[c-nsp] EIGRP routing failure

[Mark Mckillop (mmckillo)]

I'd begin with checking the K-Values match on both sides...

Router#show ip protocols

Routing Protocol is "eigrp 100 100"
  Outgoing update filter list for all interfaces is not set
  Incoming update filter list for all interfaces is not set
  Default networks flagged in outgoing updates
  Default networks accepted from incoming updates
  EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0     <=========
K-Values
  EIGRP maximum hopcount 100
  EIGRP maximum metric variance 1
  Redistributing: eigrp 100 100
  EIGRP NSF-aware route hold timer is 240s
  Automatic network summarization is in effect
  Maximum path: 4
  Routing for Networks:
  Routing Information Sources:
    Gateway         Distance      Last Update
  Distance: internal 90 external 170

Dears,

We're configuring EIGRP on both sides, customer and ISP. The customer
router are dumping the following logs. Here's an example of some logs ..
