RouterX (config)# —–> Returns to the simple configuration mode. In the case of serial interfaces, this may be an indication of lack of keepalives or mismatched encapsulation types. and the router will automatically show all the possible commands or option parameters you can apply at that specific time. To verify the configuration, we use show running-config command and the output will appear similar to as how it is shown in the below figure: Thus from the above set of examples, we have learned various commands that are commonly used for basic configuration and show configuration purposes in the routers. #1) Firstly, go to router configuration mode and enable the EIGRP on the router. Displays the system clock of the router “SnabaynetworkingR1”. So good description will come handy; it will improve your documentation and will be very effective in troubleshooting. Please use. However, in this case, the technician wants to copy a previously saved configuration from NVRAM into RAM in order to make changes to it.? So, if I do that and start looking it up, I can use the keywords to abort, which are Ctrl-Shift-6, and that thing aborts certain commands like this translation, and also ping and trace for testing. Thus we are prepared with the IP addresses to be allocated to the interfaces on Router1 and Router2. MyRouter#sh ip rip database.

To verify the configuration, we use the show running-config command and the output will appear similar to as shown in the below figure. Displays the ARP table of the router “SnabaynetworkingR1”. Branch#copy running-config startup-configDestination filename [startup-config]?Building configuration...[OK]Branch#, Branch#write memoryBuilding configuration...[OK]. Example: Router> enable Router#  configure terminal Router(config)# <—— Now router is in configuration mode. Meanwhile, we also compared the installation, configuration and use of home routers and business purpose routers. In routers, again, all interfaces that transport IP will need one; this also helps the router in defining the topology of the directly connected networks and be able to advertise those networks to other devices via routing protocols.
