Telco and ISP Dial Scenarios and Configurations
Note An offload server will always serve as the bundlemaster by bidding a higher value than the other devices.
Using L2F
L2F is a critical component used in multichassis multilink sessions. If an access server is not in charge of a multilink session, the access server encapsulates the fragmented PPP frames and forwards them to the bundlemaster using L2F. The master device receives the calls, not through the dial port (such as a dual T1/PRI card), but through the LAN or Ethernet port. L2F simply tunnels packet fragments to the device that owns the multilink session for the call. If you include an offload server in your
