MAC Address Rewriting Enabled for Layer 2 Protocol Tunneling

To configure Layer 2 protocol tunneling, you must enable MAC address rewriting by installing the destination multicast tunnel MAC address of 01:00:0c:cd:cd:d0 in the MAC table.

To enable MAC address rewriting, you can include the mac-rewrite statement at either of the following hierarchy levels:

• [edit protocols layer2-control]
• [edit routing-instances routing-instance-name protocols layer2-control]

When enabling MAC address rewriting for Layer 2 protocol tunneling, the following guidelines apply:

• You can enable Layer 2 protocol tunneling for untagged interfaces.
• You can enable Layer 2 protocol tunneling for single-identifier tagged ports.
• You cannot enable Layer 2 protocol tunneling for double identifier tagged interfaces
