EIGRP SIM
Configure the ElIGRP SIM network as shown in the topology as closely as possible.
There are errors in the configs. Your plan should be to:
Refer to the topology. Your company has connected the routers R1, R2, and R3 with serial links
R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also
interface Ethernet0/1
interface Serial1/2
1) copy the topology exactly, faithfully reproducing any errors in the configs
2) trouble shoot any problems, answering questions below, and finally,
3) correct them so that the EIGRP network is configured and works correctly

The EIGRP routing protocol is configured. You are required to troubleshoot and resolve the
EIGRP issues between the various routers. Use the appropriate show commands to
troubleshoot the issues.
