Chapter 35 Layer 2 Control Protocol Peering, Forwarding, and Tunneling

How to Configure Layer 2 Control Protocol Peering, Forwarding, and Tunneling

If an interface is configured with layer 2 protocol forwarding, then L2CP packets on the interface are flooded on to the bridge domain. The flooding follows the translations specified in interface.

Command

Purpose

 

 

 

Step 1

enable

Enables privileged EXEC mode.

 

 

Enter your password if prompted.

 

Example:

 

 

Router> enable

 

 

 

 

Step 2

configure terminal

Enters global configuration mode.

 

Example:

 

 

Router# configure terminal

 

 

 

 

Step 3

interface type number

Specifies an interface type and number and enters interface

 

 

configuration mode.

 

Example:

 

 

Router(config)# interface gigabitethernet

 

 

0/1

 

 

 

 

Step 4

l2proto-forward tagged protocol

Configures a layer 2 control protocol forwarding on an interface.

 

 

protocol—Specifies the protocol to be forwarded.

 

Example:

 

 

Router(config-if)# l2proto-forward tagged

 

 

cdp

 

 

 

 

Step 5

service instance id ethernet

Configures an Ethernet service instance on an interface.

 

 

id—Integer that uniquely identifies a service instance on an

 

Example:

interface.

 

Router(config-if)# service instance 20

 

 

ethernet
