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