Ccna-2v7.0 Case Study -rev B- Guide

ISP(config)# ip route 192.168.0.0 255.255.248.0 209.165.200.1

This is a summary route covering 192.168.0.0/21 (assuming your internal subnets fall within that range). Without this return route, traffic will go out but never come back.

On each switch, create VLANs as per case study requirements (e.g., VLAN 10 – Sales, 20 – Eng, 99 – Native). ccna-2v7.0 case study -rev b-

Trap: Remember to enable ip routing on the router and ensure each VLAN’s default gateway points to the correct subinterface IP. Also, configure DHCP helper-address if the server is on a different subnet – though in Rev B, R1 is local to all VLANs. This is a summary route covering 192
