Configuring L2TP for Enabling PPP Tunneling Within a Network

For M7i and M10i routers, you can configure Layer 2 Tunneling Protocol (L2TP) tunneling security services on an Adaptive Services Physical Interface Card (PIC) or a MultiServices PIC. The L2TP protocol allows Point-to-Point Protocol (PPP) to be tunneled within a network.

Note: For information about how to configure L2TP service, see the JUNOS Services Interfaces Configuration Guide and the JUNOS Network Interfaces Configuration Guide.

To configure L2TP, include the following statements at the [edit access] hierarchy level:

[edit access]address-pool pool-name {address address-or-prefix;address-range low <lower-limit> high <upper-limit>;}group-profile profile-name {l2tp {interface-id interface-id;lcp-renegotiation;local-chap;maximum-sessions-per-tunnel number;ppp {cell-overhead;encapsulation-overhead bytes;framed-pool pool-id; idle-timeout seconds;interface-id interface-id;keepalive seconds; primary-dns primary-dns;primary-wins primary-wins;secondary-dns secondary-dns; secondary-wins secondary-wins; }}profile profile-name {authentication-order [ authentication-methods ]; accounting-order radius;client client-name {chap-secret chap-secret;group-profile profile-name;l2tp {interface-id interface-id;lcp-renegotiation;local-chap;maximum-sessions-per-tunnel number;ppp-authentication (chap | pap);shared-secret shared-secret;}pap-password pap-password;ppp {cell-overhead;encapsulation-overhead bytes;framed-ip-address ip-address;framed-pool framed-pool;idle-timeout seconds;interface-id interface-id;keepalive seconds; primary-dns primary-dns;primary-wins primary-wins;secondary-dns secondary-dns; secondary-wins secondary-wins; }user-group-profile profile-name;}}radius-disconnect-port port-number {radius-disconnect { client-address {secret password;}}}radius-server server-address {accounting-port port-number;port port-number;retry attempts; routing-instance routing-instance-name;secret password; source-address source-address;timeout seconds;}}
