Chapter 24 Configuring PFC3BXL and PFC3B Mode Multiprotocol Label Switching
Any Transport over MPLS
• Port-based EoMPLS and VLAN-based EoMPLS are mutually exclusive. If you enable a main
interface for port-to-port transport, you also cannot enter commands on a subinterface.
To support 802.1Q-in-802.1Q traffic and Ethernet traffic over EoMPLS in PFC3BXL or PFC3B mode,
configure port-based EoMPLS by performing this task:
The following is an example of a port-based configuration:
!
EoMPLS:
router# show mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------- --------------- ---------- ----------
Fa8/48 Ethernet 75.0.78.1 1 UP
Gi7/11.2000 Eth VLAN 2000 75.0.78.1 2000 UP
Port-Based EoMPLS Config:
router# show run interface f8/48
Building configuration...
Current configuration : 86 bytes
!
interface FastEthernet8/48
no ip address
xconnect 75.0.78.1 1 encapsulation mpls
end
Sub-Interface Based Mode:
router# show run interface g7/11
Building configuration...
Current configuration : 118 bytes
!
interface GigabitEthernet7/11
description Traffic-Generator
no ip address
logging event link-status
speed nonegotiate
end
router# show run int g7/11.2000
Building configuration...
Current configuration : 112 bytes
!
interface GigabitEthernet7/11.2000
encapsulation dot1Q 2000
Command Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# interface
gigabitethernet
slot/interface
Specifies the Gigabit Ethernet interface. Make sure that the
interface on the adjoining CE router is on the same VLAN as this
PE router.
Step 3
Router(config-if)# xconnect
peer_router_id vcid
encapsulation mpls
Binds the attachment circuit to a pseudowire VC. The syntax for
this command is the same as for all other Layer 2 transports.
