Define the Encapsulation for Layer 2 Switching Cross-Connects

To configure Layer 2 switching cross-connects, configure the CCC encapsulation on the router that is acting as the switch (Router B in Figure 27).

NOTE: You cannot configure families on CCC interfaces; that is, you cannot include the family statement at the [edit interfaces interface-name unit logical-unit-number] hierarchy level.

You can configure the following encapsulations for the Layer 2 switching cross connect:

• ATM
• Ethernet
• Ethernet VLAN
• Aggregated Ethernet
• Frame Relay
• PPP and Cisco HDLC
