Sample commands output

1) Show parameters and current state of the active routing protocol process.
In EIGRP case:   AS Number   |   K-values   |  variance |  metrics   | networks  |   load-balance  |  max paths
R2# show ip protocols
Routing Protocol is "eigrp 1"
  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
  EIGRP maximum hopcount 100
  EIGRP maximum metric variance 1
  Redistributing: eigrp 1
  EIGRP NSF-aware route hold timer is 240s
  Automatic network summarization is not in effect
  Maximum path: 4
  Routing for Networks:
  Routing Information Sources:
    Gateway         Distance      Last Update           90      00:01:11
  Distance: internal 90 external 170
2) Display 2 values used in EIGRP calculations
R2# show interfaces
