Lab Topology:
Please use the following topology to complete this lab exercise:
Task 1:
Configure the hostnames on routers R1 and R2 as illustrated in the topology.
Task 2:
Configure a back-to-back Serial connection between R1 and R2. Configure the DCE interface Serial0/0 in R1 to provide clocking to R2 at a clock speed of 256 Kbps. Ignore this if you are using GNS3.
Task 3:
Configure IP addresses 192.168.254.1/30 and 192.168.254.2/30 on R1 and R2 Serial0/0 interfaces, respectively. Configure the Loopback interfaces on R1 with the IP addresses illustrated in the topology.
Task 4:
Configure a static default route from R2 pointing to R1. Ping each Loopback interface configured on R1 from R2 to verify your static route configuration.
Configuration and Verification
Task 1:
For reference information on configuring hostnames, please refer to earlier labs.
