When would you need this: When you need to setup dynamic routing for a large network and not all your routers are Cisco routers.
Special Requirements: None.
When would you need this: When are setting up your own Frame-Relay network. Usually, it is used for lab setup.
Special Requirements: A Cisco router with at least two serial interfaces.
When would you need this: When you connect two Cisco routers through a WAN connection, or back-to-back router setup.
Special Requirements: Both routers needs to be Cisco routers.
When would you need this: When your ISP gives you dynamic IP address upon each connection or you need to configure the router to obtain its interface IP address automatically.
Special Requirements: None.
Some commands in the Cisco router configuration are just irreplaceable. The ‘show’ commands are the most widely used in Cisco routers. Here is a list of the 10 mostly used of these ‘show’ commands.
When would you need this: When you are creating a WAN link. And also when the other end of a WAN link is NOT a Cisco router. Point-to-Point Protocol can be used in synchronous, asynchoronous, HSSI, and ISDN links.
Special Requirements: None.
When would you need this: When you are using ISDN links between more than two nodes.
Special Requirements: The router should have ISDN interface(s).
When would you need this: When you have ISDN WAN link and you want the router to use it.
Special Requirements: The router should have BRI interface(s).
