Applying PPP Attributes to L2TP LNS Subscribers with a User Group Profile
You can configure a user group profile that enables the LNS to apply PPP attributes to the PPP subscribers tunneled from the LAC. The user group profile is associated with clients (LACs) in the L2TP access profile. Consequently all subscribers handled by a given client share the same PPP attributes.
To configure a user group profile:
- Create the profile.[edit access]user@host# edit group-profile profile-name
- Configure the interval between PPP keepalive messages
for the L2TP tunnel terminating on the LNS.[edit access group-profile profile-name]user@host# set ppp keepalive seconds
Note: Changes to the keepalive interval in a user group profile affect only new L2TP sessions that come up after the change. Existing sessions are not affected.
- Configure PPP authentication methods that apply to tunneled
PPP subscribers at the LNS.[edit access group-profile profile-name]user@host# set ppp ppp-options chapuser@host# set ppp ppp-options pap
- Configure how long the PPP subscriber session can be idle
before it is considered to have timed out.[edit access group-profile profile-name]user@host# set ppp idle-timeout 200
| Note: You can also configure PPP attributes on a per-interface basis. See Applying PPP Attributes to L2TP LNS Subscribers Per Inline Service Interface for more information. When you configure the PPP attributes for L2TP LNS subscribers both on the si interface and in user group profiles, the inline service interface configuration takes precedence over the user group profile configuration. |
