How do I find the IP address of an interface?
Unzip the file and open the config file for the router.

What is an interface IP address?
The IP address of network interface is in most cases a dynamic, private IP address which was given to the network interface by the DHCP (server or router).

Why does every interface at the router need an IP address?
The Router will have an “arm” inside each network — or as we call it, an interface. And the way an interface exists within a network is by assigning it an IP address within the network. Hence, when configuring a router, each interface receives an IP address to identify the networks which that Router belongs within.
How do I find my router interface?
Use the show interfaces EXEC command to display statistics for all interfaces configured on the router or access server.
Can You Ping the interface from the router itself?
I read your post and I understand you are pinging the router interface from the router itself. The reason I asked is because in a frame relay point to multipoint environment you can not ping your own interface unless you do a mapping if the IP address of the interface to a DLCI number. 02-07-2010 07:17 PM
