Good day. There is a Cisco 891-f router. It is necessary with its help to organize a local network in this way:
- Interfaces Gigabit Ethernet 0, 4, 5 Look in one subnet with the address 192.168.50.1/24
- Gigabit Ethernet 1 interface - to the subnet with the address 192.168.55.1/24
- Gigabit Ethernet 2 interface - to the subnet with the address 192.168.60.1/24
- Interface Gigabit Ethernet 8 - to the provider
Since the GigabitEthernet 0-7 interfaces are represented as second-level interfaces, Vlan interfaces were created to support the IP protocol and the corresponding interfaces of the router land on it. It is not possible to test the network performance at the moment, so I wanted to find out what needs to be added to the configuration file for this network to work.
