CCIE Lab Diary – EIGRP Lab


Implement EIGRP in a 9 router network with frame relay as the underlying L2 encapsulation to demonstrate protocol behaviours in a NBMA environment. Also involves tweaking of various parameters using summarization, redistribution, various stub types, distribute lists etc.

Technologies involved:

  • Serial interfaces
  • Ethernet interfaces
  • Frame Relay

Logical topology


Pitfalls/Things to watch out for

  • Frame Relay PVC issues
  • EIGRP timers on “slow” links, might want to tune them
