OSPF Troubleshooting Lab (simple)

The necessary networking has been completed at each location,
and the routers have been configured with single area OSPF as the routing protocol.

The Boston router was recently installed but connectivity is not complete because of incomplete routing tables.

Identify and correct any problem you see in the configuration.

Note: The OSPF process must be configured to allow interfaces in specific subnets to participate in the routing process.

EIGRP ROUTING - Advanced

TASKS

1. Configure MD5 authentication
   
2. Configure a router id
   
3. Configure eigrp bandwidth percentage at 90%
   
4. Configure the bandwidth on the interfaces (optional)
   
5. Configure the hello interval 10s & Hold time 30s as appropriate with norms.
   
6. Disable logging of neighbor changes & warnings
   
7. Configure the default route on HQ to the ISP.
   
8. Propagate the default route from HQ to the zones
   
9. Configure the default route on the Zone routers & propagate it to the sub zones.
   
10. Routing updates should not propagate to the ISP or the Lans
    
11. Ensure that each Zone & Sub zone networks do not propagate beyond HQ to the other zones.
    
12. Use PPP with CHAP authentication.
    

On the Subzone routers

1. Configure the sub-zone routers as stubs
   
2. Do not allow exterior routes to be advertised in updates.
   
3. Influence the metric calculation to prefer the longer route to access the zone LAN´s

RIP ROUTING

RIP V2 ROUTING

---------------------------------------------- 

Guidelines

1. Perform basic configuration +

2. Direct RIP to only send unicast updates to the zone router.

3. Configure MD5 AUTHENTICATION between neighbors.

4. Propagate the DEFAULT ROUTE from HQ.

5. Disable Auto Summarization.

6. Routing Updates Should not propagate to the ISP or the LANS

7. Alter RIP to prefer the longer route within the zone.

8. Ensure that the LANS do not propagate beyond HQ to the other regions.

9. Verify connectivity pings should work from end to end.

STATIC & SUMMARY ROUTING

Objective :

1. PERFORM BASIC ROUTER CONFIGURATION
2. CONFIGURE TO SEND CDP UPDATES ACROSS SERIAL LINKS ONLY
3. CONFIGURE STATIC ROUTES WITH NEXT HOP or EXIT INTERFACE
4. CONFIGURE DEFAULT ROUTES.
5. CONFIGURE SUMMARY ROUTES FOR THE LAN NETWORKS.
6. VERIFY CONNECTIVITY. ALL HOSTS SHOULD BE ABLE TO PING ALL THE OTHER HOSTS & THE SERVER.

Hello Fellow Internauters & CCNA Aspirers.

During my CCNA pursuit I have spent hours "googling¨ for LABS that go beyond the normal curriculum of the course in order to get a broad understanding of the concepts and prepare me for my next level (CCNA specialization / CCNP ). The many forums and blogs have helped me a lot. In these forums i found posts relating to specific problems. Inspired by the lack of coherency for a novice, during my studies I have developed the following labs for each stage of learning. 

Thanks for your interest
