MCE configuration commands
This chapter describes only the commands related to the MCE feature. For information about the routing
protocol configuration commands in the configuration examples, see Layer 3—IP Routing Command
Reference.
The term "interface" in this chapter collectively refers to Layer 3 interfaces, including VLAN interfaces,
Layer 3 Ethernet interfaces, and Layer 3 aggregate interfaces. You can set an Ethernet port as a Layer 3
interface by using the port link-mode route command (see Layer 2—LAN Switching Configuration
Guide).
