Ethernet interfaces, VLAN
interfaces, and ATM interfaces use
PPP as the link layer protocol.
Configuring PPP authentication
You can configure several authentication modes simultaneously. In LCP negotiation, the authenticator
negotiates with the peer in the sequence of configured authentication modes until the LCP negotiation
succeeds. If the response packet from the peer carries a recommended authentication mode, the
authenticator directly uses the authentication mode if it finds the mode configured.
