Example for Configuring a Local CCC

A local Circuit Cross Connect (CCC) is a connection between two CEs connected to the same PE. The PE functions similar to a Layer 2 switch to directly transmit packets without using LSPs.

Networking Requirements

On the network shown in Figure 1, CE1 and CE2 connect to a PE through GE interfaces.

A local CCC is set up between CE1 and CE2.

Figure 1 Networking for a local CCC

Interfaces 1 and 2 in this example represent GE 0/1/0 and GE 0/1/8, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

Configure basic MPLS functions on the PE and enable MPLS L2VPN.
Establish a local CCC between CE1 and CE2 on the PE. A local CCC is bidirectional, and only one connection is required.

Data Preparation

No data is required except interface IP addresses.

Procedure

Configure CEs.

# Configure CE1.

<HUAWEI> system-view
[~HUAWEI] sysname CE1
[*HUAWEI] commit
[~CE1] interface gigabitethernet 0/1/0
[*CE1-GigabitEthernet0/1/0] ip address 10.1.1.1 24
[*CE1-GigabitEthernet0/1/0] undo shutdown
[*CE1-GigabitEthernet0/1/0] commit
[~CE1-GigabitEthernet0/1/0] quit

# Configure CE2.

<HUAWEI> system-view
[~HUAWEI] sysname CE2
[*HUAWEI] commit
[~CE2] interface gigabitethernet 0/1/0
[*CE2-GigabitEthernet0/1/0] ip address 10.1.1.2 24
[*CE2-GigabitEthernet0/1/0] undo shutdown
[*CE2-GigabitEthernet0/1/0] commit
[~CE2-GigabitEthernet0/1/0] quit

Configure the PE.

# Configure an LSR ID and enable MPLS and MPLS L2VPN.

<HUAWEI> system-view
[~HUAWEI] sysname PE
[*HUAWEI] commit
[~PE] interface loopback 1
[*PE-LoopBack1] ip address 1.1.1.9 32

[*PE] mpls
[*PE-mpls] quit
[*PE] mpls l2vpn
[*PE-l2vpn] quit
[*PE] interface gigabitethernet 0/1/0
[*PE-GigabitEthernet0/1/0] undo shutdown
[*PE-GigabitEthernet0/1/0] quit
[*PE] interface gigabitethernet 0/1/8
[*PE-GigabitEthernet0/1/8] undo shutdown
[*PE-GigabitEthernet0/1/8] commit
[~PE-GigabitEthernet0/1/8] quit

# Establish a local CCC between CE1 and CE2.

[*PE] ccc ce1-ce2 interface gigabitethernet 0/1/0 out-interface gigabitethernet 0/1/8
[*PE] commit

Verify the configuration.

After completing the configurations, check CCC information on the PE. The command output shows that a local CCC has been established and its status is Up.

<PE> display vll ccc
total  ccc vc : 1
local  ccc vc : 1,  1 up
remote ccc vc : 0,  0 up

name: ce1-ce2, type: local, state: up,
intf1: GigabitEthernet0/1/0 (up),access-port: false

intf2: GigabitEthernet0/1/8 (up),access-port: false
VC last up time : 2012/03/08 05:13:10
VC total up time:  0 days, 0 hours, 0 minutes, 14 seconds

Run the display l2vpn ccc-interface vc-type all command. The command output shows that the VC type is ccc and the VC status is up.

<PE> display l2vpn ccc-interface vc-type all
