Configuring L2F
Misconfiguration is the most common cause of L2F tunnel failure. Although L2F configuration is not a primary goal of this chapter, this section discusses basic L2F configuration.
The next two sections step through the configurations for the NAS and the Home Gateway.
Configuring the L2F NAS
The configuration for the NAS discussed here assumes a typical hardware configuration including either E1 or T1 ISDN Primary Rate Interfaces (PRIs), together with asynchronous digital (MICA) modems.
Configuration of the NAS involves nine basic steps, as summarized in the list that follows:
Step 1. | Configure the E1/T1 controllers. |
Step 2. | Configure global ISDN parameters. |
Step 3. | Configure the D channels. |
Step 4. | Configure parameters for asynchronous ... |
