1. The document describes configuring EIGRP routing on a network topology. This includes configuring EIGRP routing processes and interfaces, adjusting EIGRP timers, enabling authentication, setting metric weights, redistributing routes between EIGRP processes, summarizing routes, and filtering routes.

1. Lab 29: EIGRP-II
Task
1. Configure IP address as per given in topology.
2. Configure Eigrp as per given in topology and also introduce all the loopback in Eigrp.
3. Change Hello and Hold timer in Eigrp 200 to 2 and 6 respectively.
4. Use MD5 authentication between R5 and R4. Use keystring as N3TW@x.
5. Use Metric weight in eigrp 100 as 0 1 0 1 1 0.
6. Make sure all routers receive all the routes.
7. Manual Route summarization on R5 and R7 for loopbacks.
8. Make sure that R5 receive R7 loopback route from Se1/0.
