Configuration Tasks for L2VPN
Set the experimental bits in both the VC label and the LSP tunnel label. You set the experimental bits in
the VC label, because the LSP tunnel label might be removed at the penultimate router.
To set the experimental bits, enter the following commands beginning in global configuration mode:
Table 20-7 Commands Supported to Change EXP Bits
Transport Type Supported Commands
ATM AAL5 SDU support over MPLS
Ethernet over MPLS:
Port mode
Frame Relay over MPLS:
DLCI-to-DLCI connections
Port-to-port connections
HDLC over MPLS
PPP over MPLS
set mpls experimental
match any
Ethernet over MPLS:
VLAN mode
set mpls experimental
match cos
Command Purpose
Step 1
Router(config)# class-map class-name
Specifies the user-defined name of the traffic class and enters
class map configuration mode.
Step 2
For all transport types except Ethernet over MPLS in
VLAN mode:
Router(config-cmap)# match any
For Ethernet over MPLS in VLAN mode only:
Router(config-cmap)# match cos cos-value
Specifies that all packets are matched.
cos-value is from 0 to 7; up to four CoS values can be
specified in one match cos statement.
Step 3
Router(config-cmap)# policy-map policy-name
Specifies the name of the traffic policy to configure and
enters policy map configuration mode.
Step 4
Router(config-pmap)# class class-name
Specifies the name of a predefined traffic class, which was
configured with the class-map command, used to classify
traffic to the traffic policy. Enters policy-map configuration
mode.
Step 5
Router(config-pmap-c)# set mpls experimental
value
Designates the value to which the MPLS bits are set if the
packets match the specified policy map.
Step 6
Router(config-pmap-c)# exit
Exits policy map configuration mode.
Step 7
Router(config-pmap)# exit
Exits policy map mode.
Step 8
Router(config)# interface slot/port
Specifies the interface and enters interface configuration
mode.
Step 9
Router(config-if)# service-policy input
policy-name
Attaches a traffic policy to an interface.
