Lab Overview Trouble Ticket A—EIGRP Adjacency Issues
– There is no connectivity to the additional IP subnet being deployed on a LAN segment between routers R2 and R4.
– There are issue with the EIGRP adjacency to router BBR1.– A configuration was applied that should have improved the
metric calculation on R4, but instead resulted in no connectivity from that router.
– Summarization was configured, but is not working as expected.
Trouble Ticket B—Limited Connectivity– A new spoke location, router R3, was deployed with no
connectivity to the LAN subnets attached to routers R2 and R4.

Instructions Create the troubleshooting plan. Verify that you can see no more errors for the entries generated
on routers R2 and R4. Verify that EIGRP adjacency on the LAN segment between
routers R2 and R4 has been formed. Verify that the secondary IP address from the LAN segment is
also present on router R1, and that you can ping the IP addresses from that subnet
Verify that EIGRP adjacency has been formed between routers R1 and BBR1.
Verify that routers in your pod have received subnets 192.168.x.0/24, announced by router BBR1.

Instructions (Cont.) Verify that routers have specific information about every subnet in
your network and that you have connectivity to those subnets. Verify that router R3 receives IP routing information for the IP
subnets located on the LAN segment between routers R2 and R4. Verify that you can ping the IP addresses from the IP subnets
located on the LAN segment between routers R2 and R4.

Summary Connectivity issues, wrong authentication, and metric
configuration result in EIGRP adjacency issues. Incorrectly configuring a newly deployed site can lead to limited
connectivity.
