Once you define what constitutes interesting traffic, you must provide the interface responsible for initiating the call with all the parameters necessary to reach the destination. The
dialer map
command identifies destination router information, such as the phone number to dial:
Router(config-if)#dialer map protocol next-hop-address
[name hostname] [broadcast] dial-string
The
dialer map
command has many other optional parameters available to it.
However, these commands will
suffice for most connections.
What are we mapping?
Cisco commands
often contain the word “map,” which is used to map statically
Layer 2 addresses to Layer 3 addresses. For example, the command frame-relay
map is used to define a Layer 3
next-hop-address to its Layer 2 address-in this case, a DLCI number.
With a dialer-map
statement, you bundle a Layer 3 address (IP in this chapter) to a
dial-up Layer 2 address (which, in this case, is a phone number).
