Configuring L2PT Tunneling
This section describes the commands used to configure Layer 2 Protocol Tunneling
(L2PT).
l2protocol-tunnel
tunnel-dmac
This command configures the destination address for Layer 2 Protocol Tunneling
(L2PT). Use the
no
form to restore the default setting.
Syntax
l2protocol-tunnel tunnel-dmac
mac-address
mac-address
– The switch rewrites the destination MAC address in all
upstream L2PT protocol packets (i.e, STP BPDUs) to this value, and forwards
them on to uplink ports. The MAC address must be specified in the format
xx-xx-xx-xx-xx-xx or xxxxxxxxxxxx.
Default Setting
01-12-CF-.00-00-02, proprietary tunnel address
Command Mode
Global Configuration
Command Usage
◆
When L2PT is not used, protocol packets (such as STP) are flooded to 802.1Q
access ports on the same edge switch, but filtered from 802.1Q tunnel ports.
This creates disconnected protocol domains in the customer’s network.
◆
L2PT can be used to pass various types of protocol packets belonging to the
same customer transparently across a service provider’s network. In this way,
normally segregated network segments can be configured to function inside a
common protocol domain.
◆
L2PT encapsulates protocol packets entering ingress ports on the service
provider’s edge switch, replacing the destination MAC address with a
proprietary MAC address (for example, the spanning tree protocol uses 10-12-
CF-00-00-02), a reserved address for other specified protocol types (as defined
in IEEE 802.1ad – Provider Bridges), or a user-defined address. All intermediate
switches carrying this traffic across the service provider’s network treat these
