The Mysterious World of NetPractice
- Routing protocols: Configure and simulate various routing protocols, such as OSPF, EIGRP, and RIP.
- Network security: Configure firewalls, access control lists (ACLs), and other security features to protect your network.
- Switching: Configure and simulate switching networks, including VLANs, trunking, and Spanning Tree Protocol (STP).
- Network A:
192.168.0.0/25(hosts: .1 – .126) - Network B:
192.168.0.128/25(hosts: .129 – .254) - Router uses
