Comprehensive experiment of EIGRP

Experiment topology diagram:

Experiments show: The three-tier architecture, R1 and R2 for Headquarters, R3 and R4 for the region, R5 and R6 as branch offices, R7 analog Internet routers

Experiment Request:

1. Branch to the headquarters or other areas to use R1 as the main link, R2 become a standby link

2.IP the hierarchy of address, to be able to achieve routing summary

3. The branch of the router as a stub node, to avoid other routers to send queries to the branch

4. Make the R7 an Internet router, sending a default route from R2 to another branch site

5. Completion of validation between R1 and R2

Steps:

1. To use R3 and R4 to reach headquarters using R1 as the primary link, you need to modify the bandwidth or latency to increase the metric value of the link that connects R2

2. Routing totals can be implemented at any router, but the regional routing rollup reduces CPU and memory usage and keeps the topology stable.

3. Configure R5 and R6 to not accept queries

4. Make a static route in R2 to point to R7 7.7.7.7 and reroute this route to the EIGRP network

5. Use MD5 to authenticate between R1 and R2
