# Before You Configure L2TP Dial-Out

Create a profile that the router uses to create the dynamic PPP and IP interfaces on the LNS. The profile specifies parameters that are common to all dial-out sessions that use the profile. The following is an example of a typical profile configuration.

1. Create a profile.
   host1(config)#profile dialOut host1(config-profile)#
2. Specify the interface used for dialout.
   host1(config-profile)#ip unnumbered loopback 0/0
3. Specify the virtual router for the dial-out user’s IP interface.
   host1(config-profile)#ip virtual-router lns
4. Specify the authentication mechanism.
   host1(config-profile)#ppp authentication chap
