Lab 3: EIGRP

Task

Topology

1. Configure IP address on all the Routers.
2. Enable EIGRP on all the Routers.
3. R1 and R7 advertise not summarized routes. (Do verification after this task)
4. Change R5 hop count to 1.
5. Find the possible ways to Ping R5 to R1, R2, R7 and R6 loopback. (You are not allowed to change hop count on R5)
6. Advertise R2 and R7 Loopback in EIGRP via manual summarization.

Solution

Task 1: Configure IP address on all the Routers.
