Study Notes
Basic Router Configuration
- Routing packets is similar to a relay race, with each router forwarding packets to the next in line.
- Routers use routing tables to forward packets to other networks.
- Routers must be configured to create routing tables and forward packets.
Configuring Router Interfaces
- To enable a router interface, use the no shutdown command.
- Use the description command to provide information about the interface, such as the type of network connected.
- The no shutdown command activates the interface and is similar to powering it on.
- The interface must be connected to another device, such as a switch or another router, for the physical layer to be active.
- On inter-router connections without an Ethernet switch, both interfaces must be configured and enabled.
- Several commands can be used to verify interface configuration, including show ip interface brief, show ipv6 interface brief, show ip route, show ipv6 route, show interfaces, show ip interface, and show ipv6 interface.
Configuring Initial Router Settings
- When configuring a router, complete the following tasks:
- Configure the device name.
- Secure privileged EXEC mode.
- Secure user EXEC mode.
- Secure remote Telnet/SSH access.
- Secure all passwords in the config file.
- Provide legal notification.
- Save the configuration.
Configuring the Default Gateway
- For end devices to communicate over a network, they must be configured with the correct IP address information, including the default gateway address.
- The default gateway address is typically the router interface address for the router connected to the local network.
- The IP address of the host device and the router interface address must be in the same network.
- When a network has multiple routers, select one to be the default gateway router.
Default Gateway on a Switch
- A switch typically functions at Layer 2 and does not require an IP address.
- To remotely manage a switch, configure a switch virtual interface (SVI) with an IPv4 address and subnet mask on the local LAN.
- The switch also requires a default gateway address to be remotely managed from another network.
- Use the ip default-gateway ip-address global configuration command to configure an IPv4 default gateway on a switch.
Useful Show Commands
- show running-config: Displays the current configuration running on the device.
- show startup-config: Shows the configuration stored in NVRAM that will be used on the next reboot.
- show version: Provides details about the IOS version, system uptime, and hardware information.
- show interfaces: Displays detailed information about all network interfaces, including status and statistics.
- show ip interface brief: Summarizes the status of all interfaces, including IP addresses and operational status.
- show vlan: Lists VLAN information and status.
- show mac address-table: Displays the MAC address table, showing which MAC addresses are associated with which ports.
