PPP authentication using PAP or CHAP takes place between directly connected routers only. When using a public

IP Network to connect sites this authentication takes place between the customers router and the service

provide router that it is connected to. In some circumstances it is desirable to authenticate between the

customer owned routers, jumping over all the intermediary routers of the service provide network. Layer 2

Tunneling Protocol allow this to happen by facilitating a two stage authentication, firstly with the service

provider router then the customer router on the remote network.
