Configuring the Layer 2 Protocol to be Tunneled

To configure the protocol that is tunneled by the Layer 2 protocol tunnel, include the protocol (cdp | stp | vtp) statement at the [edit protocols layer2-control mac-rewrite interface ge-fpc/pic/port] hierarchy level:

[edit protocols layer2-control mac-rewrite interface ge-fpc/pic/port]
protocol (cdp | stp | vtp);

For each protocol specified, a static destination MAC address corresponding to the protocol being tunneled is installed in the MAC table.

When CDP, STP, or VTP is configured for tunneling on a customer-facing port in a provider bridge, the corresponding protocol should not be enabled for operation on that interface.
