Configuring Multiprotocol Encapsulation over ATM

Multiprotocol Encapsulation over ATM Configuration Example

The following example shows how to configure for multiprotocol encapsulation over ATM with two routers and a ATM switch router.

The ATM switch router has an ATM router module in slot 0, a Fast Ethernet interface module in slot 1, and an ATM interface module in slot 3. One router has an ATM interface processor in slot 3. The other router has a Fast Ethernet interface module in slot 2.

Figure 24-6shows an example of an RFC 1483 network.
