Configuring Ethernet VLAN Circuits
You can configure Ethernet virtual local area network (VLAN) circuits on Fast Ethernet,
Gigabit Ethernet, and aggregated Ethernet interfaces. For Ethernet VLAN circuits,
specify the encapsulation by including the
interfaces interface-name]
device. You must also enable VLAN tagging. To do this, include the following
statements:
On the logical interface, include the following statements:
You can include the logical interface statements at the following hierarchy levels:
Ethernet interfaces in VLAN mode can have multiple logical interfaces. For
encapsulation type
and VLAN IDs 512 through 1023 are reserved for CCC VLANs. For encapsulation

for tagging the priority of frames.
Defining the Connection for Switching Cross-Connects
To configure Layer 2 switching cross-connects, define the connection between the
two circuits. You configure this on the router that is acting as the switch (Router B
