| CLI Section | CLI command | Purpose |
|---|---|---|
| Router # | enable | When the router is not set to enabled, configurations will not take effect and it will be unable to link anything. |
| Router # | "Conf T" &OR "Configure Terminal" | This will pull up the terminal section which will allow you to modify ports & interfaces |
| Router(config) # | "interface fa0/0" | Accesses the interface of fastethernet 0/0. This by proxy allows for the implementation of IP space. |
| Router(config) # | interface range fa0/0-6 | Access the first 6 FA ports for further configuration |
| Router(config) # | int vlan [vlan #] | Goes to the setup interface of the Vlan allowing for further modifications. |
| Router(config) # | router rip | transfers you to the routing section |
| Any | exit | Brings you to the previous menu. |
| CLI Section | CLI command | Purpose |
|---|---|---|
| Router(config-if) # | ip address [network ID] [netMask] | Sets the ip of a specified port / vlan to a specified network ID. |
| switch(config-router)# | version 2 | This sets RIP to Version 2 which may fix potential issues. |
| switchport access vlan 100 | Sets a specified port / port range to be subject to rules relating to vlan 100. This includes ip specifications and is used for DHCP allocation. | |
| Router# | "show ip int" &OR "show ip interface" | this shows all configured interfaces and their leased IP address space. |
| Router# | show ip int br | inc Vlan | This command shows all current VLAN configurations relating to the interfaces present on the router. |
| Router# | copy run start | This saves a copy of the current status of the router. |
| CLI Section | CLI command | Purpose |
|---|---|---|
| Router(config-if) | ip helper-address 10.10.6.2 | When set on Vlans, it helps identify a singular ip space all devices should communicate with for IP allocation regardless of network. |
| CLI Section | CLI command | Purpose |
|---|---|---|
| (config)# | interface serial 0/0/0 | After setting interfaces, you must confirm the serial ports have addresses leased. The command used to access the interface is as such |
| (config-if)# | clock rate 64000 | This sets the data transfer rate for the serial cabling to 64000 |
| (config-if)# | bandwidth 64 | This command sets the bandwidth of the serial cable to 64. |
| (config)# | ip nat pool [insert-pool-name] [Public-facing-IP] [Public-facing-IP] 255.0.0.0 | sets the ip face for the outfacing web connection |
| (config)# | ip route [Destination-Address] [Subnet-Mask] [Next-Hop] | This command manually configures and edits a specified routing table in order to tell it to send traffic meant for the destination address to a specified hop location (in this case a serial connector) |
| (Config-if)# | ip nat inside | This command translates IP's from public to private so external devices can communicate with internal devices |
| (Config-if)# | ip nat outside | This command translates IP's from private to public so internal devices can contact external devices. |
| (config)# | ip nat inside source static [Private-IP] [Public-IP] | this command forces nat to use the static public-IP of X when the private IP wishes to communicate with a device on another network. |
| CLI Section | CLI command | Purpose |
|---|---|---|
| (config)# | ip route 0.0.0.0 0.0.0.0 [Gateway-IP] | This sets all traffic as being able to access the default route/Gateway |
| (config)# | ip nat pool test 30.0.0.120 30.0.0.120 netmask 255.0.0.0 | This creates an IP pool of a singular IP for devices to be able to pool from. |
| (config)# | access-list 1 permit [Private-IP] [Reflected-SubMask] | This command states that the Private-IP space should be added to a list of IP's. |
| (config)# | ip nat inside source list 1 pool test overload | This command takes the contents of your "access-list" [the private IP space] and sets it to use the pool created for its outgoing network. |
| # | Show ip nat translations | This command shows all of the IPs that have communicated with outgoing networks and on what port they have communicated from |
| CLI Section | CLI command | Purpose |
|---|---|---|
| #(config) | router ospf [Insert-Instance] | This command enables OSPF on a router. Where it states [Insert-Instance] replace that with a number such as 1 |
| #(config-router) | network [destination-network] [inverted-CIDR] area 0 | This command enables the destination address to be routed to as it is a member of area 0. area is simply a location to state where devices can listen and talk to each other |
| CLI Section | CLI command | Purpose |
|---|---|---|
| #(config) | ipv6 general-prefix [Prefix-Name] [IPV6-Network-Adress::64] | Sets the general IPv6 network for a specific router. Must be done in CLI |
| #(config)# | ipv6 unicast-routing | Enables IPv6 Routing on the network router. |
| (config-if)# | ipv6 address [IPV6-Network-Address::64] | When done on a FA/GE port, it sets the IP of the connection to a IPv6 network address. |
| (config-if)# | ipv6 address autoconfig | When done on a FA/GE that has had the general-prefix set; the IPv6 address will be automatically configured |
| (config-if)# | ipv6 rip process[insert#] enable | Used to enable RIP routing with ipv6. This will allow for the creation of an ipv6 routing table |
