Providing Dial-Out Access Without LSDO (Direct ISDN)
Sometimes the VRF-aware LSDO solution might not be applicable. This occurs when there is direct ISDN dial-out from the VHG or when the number of dial-out customers is small and contained to a single LAC/LNS pair (therefore, not many routers need to be configured). The L2TP tunnels for dial-out can be statically configured.
NOTE
If VRF-aware LSDO was not used, then a dialer profile configuration for each remote destination is required on every VHG or NAS (for direct ISDN) that provided dial-out services. In a large network, this would involve a considerable amount of operational overhead.
The static dialer profile configuration (no AAA servers are used) is shown in Example 2-34. This configuration ...
