Description

Configure the protocol to be tunneled on an interface using Layer 2 protocol tunneling (L2PT). To enable tunneling multiple protocols, include multiple protocol statements.

Not all protocols listed in the Options section can be tunneled on all devices. The Syntax and Release Information sections list the available options for the protocols that different devices can tunnel as of a particular Junos OS release.

When a service provider edge (PE) port configured for L2PT receives a control packet for a supported protocol, the PE device rewrites the multicast destination MAC address with the predefined multicast tunneling MAC address 01:00:0c:cd:cd:d0. The packet travels across the provider network transparently to the other end of the tunnel, and the destination device restores the original multicast destination MAC address to deliver the packet at its destination.

Options

cdp—Tunnel the Cisco Discovery Protocol (CDP).

elmi—Tunnel Ethernet Local Management Interface (E-LMI) packets.

gvrp—Tunnel Generic Attribute Registration Protocol (GARP) VLAN Registration Protocol (GVRP) packets.

ieee8021x—Tunnel IEEE 802.1X authentication packets.

ieee8023ah—Tunnel IEEE 802.3AH Operation, Administration, and Maintenance (OAM) link fault management (LFM) packets.

lacp—Tunnel Link Aggregation Control Protocol (LACP) packets.

lldp—Tunnel Link Layer Discovery Protocol (LLDP) packets.

mmrp—Tunnel Multiple MAC Registration Protocol (MMRP) packets.

mvrp—Tunnel Multiple VLAN Registration Protocol (MVRP) packets.

pvstp—Tunnel VLAN Spanning Tree Protocol (VSTP), Per-VLAN Spanning Tree (PVST), and Per-VLAN Spanning Tree Plus (PVST+) Protocol packets.

stp—Tunnel packets for all versions of Spanning-Tree Protocols.

udld—Tunnel Unidirectional Link Detection (UDLD) packets.

vstp—Tunnel VLAN Spanning Tree Protocol (VSTP) packets.

vtp—Tunnel VLAN Trunking Protocol (VTP) packets.
