Configuring Layer 2 Protocol Tunneling

You can configure Layer 2 protocol tunneling under the following hierarchy levels:

• [edit ]
• [edit routing-instances routing-instance-name]

To configure Layer 2 protocol tunneling:

1. Enable MAC address rewriting for Layer 2 protocol tunneling:
   
   

   [edit ... ]
user@host# edit protocols layer2-control mac-rewrite
2. Configure the Layer 2 protocol tunnel interface:
   
   

   [edit ... protocols layer2-control mac-rewrite]
user@host# edit interface ge-fpc/pic/port
3. Configure the Layer 2 protocol to be tunneled:
   
   

   [edit ... protocols layer2-control mac-rewrite interface ge-fpc/pic/port]
user@host# set protocol (cdp | stp | vtp)

4. Verify the configuration:

   user@host> show ... protocols protocols {layer2-control {mac-rewrite {interface ge-fpc/pic/port {protocol (cdp | stp | vtp);}}}}
