Deleting a VLAN
To delete a VLAN for a static or dynamic L2TPv3 tunnel session, do the following:
1. Make sure the CLI is in Configuration mode.
2. Delete the tunnel by typing:
no tunnel l2tpv3 [ static | dynamic ] tunnel tunnel-name session tunnel-session vlan vid
Where:
• tunnel-name is the name of the tunnel
• tunnel-session is the name of the tunnel session
• vid is the VLAN ID for the routable logical interface

Managing GOOSE Tunnels
The GOOSE tunnel feature provides the capability to bridge GOOSE frames over a Wide Area Network (WAN).
GOOSE tunnels provide the following features:
• GOOSE traffic is bridged over the WAN via UDP/IP.
• One GOOSE traffic source can be mapped to multiple remote router Ethernet interfaces in mesh fashion.
• To reduce bandwidth consumption, GOOSE daemons may be located at each of the legs and at the center of a
star network. The centrally located daemon will accept GOOSE packets and re-distribute them.
• Statistics report availability of remote GOOSE daemons, packet counts and Round Trip Time (RTT) for each
remote daemon.
• When the Virtual Router Redundancy Protocol (VRRP) is employed, GOOSE transport is improved by sending
redundant GOOSE packets from each VRRP gateway.
• You can enable GOOSE forwarding by configuring a generic Layer 2 tunnel. When configured, the device listens
for GOOSE packets on one VLAN and forwards them to another VLAN.
The GOOSE protocol is supported by the Layer 2 Tunnel Daemon. The daemon listens to configured Ethernet
interfaces and to the network itself (i.e. for tunnel connections from other daemon instances) on a configurable
UDP port.
The Media Access Control (MAC) destination address of frames received from Ethernet is inspected in order to
determine which GOOSE group they are in. The frames are then encapsulated in network headers and forwarded
(with MAC source and destination addresses intact) to the network as GOOSE packets.
IEC61850 recommends that the MAC destination address should be in the range 01:0c:cd:01:00:00 to
01:0c:cd:01:01:ff.
GOOSE packets received from the network are stripped of their network headers and forwarded to Ethernet
ports configured for the same multicast address. The forwarded frames contain the MAC source address or the
originating device, and not that of the transmitting interface. The VLAN used will be that programmed locally for
