Evaluation Order for Matching Client Information in PPPoE Service Name Tables

When the router receives a service request from a PPPoE client, it evaluates the entries configured in the PPPoE service name table to find a match for the client’s ACI/ARI information so it can take the appropriate action.

The order of evaluation is as follows:

  1. The router evaluates the ACI/ARI information configured for the any service entry, and ignores the contents of the service name tag transmitted by the client.

  2. If no match is found for the client information, the router evaluates the ACI/ARI information for the empty service entry and the named service entries. If an ACI/ARI pair is not configured for these service entries, the router evaluates the other attributes configured for the empty service and named services.

  3. If there is still no match for the client information, the router evaluates the other attributes configured for the any service entry, and ignores both the ACI/ARI information for the any service and the contents of the service name tag transmitted by the client. If the any service is configured for the default action, drop, the router drops the PADR packet. If the any service is configured for a nondefault action (terminate or delay), the router evaluates the other attributes configured for the any service.
