Configuring a remote CCC connection

Create a remote CCC connection between PE 1 and PE 2 so VLAN 10 on CE 1 can communicate with VLAN 10 on CE 2.

Before you perform the following configurations, configure VLANs and add ports to VLANs on switches.

1. Configure CE 1.

   <CE1> system-view
   [CE1] interface ten-gigabitethernet 1/0/1
   [CE1-Ten-GigabitEthernet1/0/1] port link-type trunk
   [CE1-Ten-GigabitEthernet1/0/1] port trunk permit vlan 10
   [CE1-Ten-GigabitEthernet1/0/1] quit
   

2. Configure PE 1:

   # Configure an LSR ID.

   <PE1> system-view
   [PE1] interface loopback 0
   [PE1-LoopBack0] ip address 192.2.2.2 32
   [PE1-LoopBack0] quit
   [PE1] mpls lsr-id 192.2.2.2
   

   # Enable L2VPN.

   [PE1] l2vpn enable
   

   # Configure VLAN-interface 20 (the interface connected to P), and enable MPLS on the interface.

   [PE1] interface vlan-interface 20
   [PE1-Vlan-interface20] ip address 10.1.1.1 24
   [PE1-Vlan-interface20] mpls enable
   [PE1-Vlan-interface20] quit
   

   # Create service instance 10 on Ten-GigabitEthernet 1/0/1 to match packets that have an outer VLAN ID of 10.

   [PE1] interface ten-gigabitethernet1/0/1
   [PE1-Ten-GigabitEthernet1/0/1] service-instance 10
   [PE1-Ten-GigabitEthernet1/0/1-srv10] encapsulation s-vid 10
   [PE1-Ten-GigabitEthernet1/0/1-srv10] quit
   [PE1-Ten-GigabitEthernet1/0/1] quit
   

   # Create a cross-connect group named ccc, create a remote CCC connection that has incoming label 101, outgoing label 201, and next hop 10.1.1.2, and bind service instance 10 on Ten-GigabitEthernet 1/0/1 to the CCC connection.

   [PE1] xconnect-group ccc
   [PE1-xcg-ccc] connection ccc
   [PE1-xcg-ccc-ccc] ccc in-label 101 out-label 201 nexthop 10.1.1.2
   [PE1-xcg-ccc-ccc] ac interface Ten-GigabitEthernet 1/0/1 service-instance 10
   [PE1-xcg-ccc-ccc] quit
   [PE1-xcg-ccc] quit
   

3. Configure the P device:

   # Configure an LSR ID.

   <P> system-view
   [P] interface loopback 0
   [P-LoopBack0] ip address 192.4.4.4 32
   [P-LoopBack0] quit
   [P] mpls lsr-id 192.4.4.4
   

   # Configure VLAN-interface 20 (the interface connected to PE 1), and enable MPLS on the interface.

   [P] interface vlan-interface 20
   [P-Vlan-interface20] ip address 10.1.1.2 24
   [P-Vlan-interface20] mpls enable
   [P-Vlan-interface20] quit
   

   # Configure VLAN-interface 30 (the interface connected to PE 2), and enable MPLS on the interface.

   [P] interface vlan-interface 30
   [P-Vlan-interface30] ip address 10.2.2.2 24
   [P-Vlan-interface30] mpls enable
   [P-Vlan-interface30] quit
   

   # Configure a static LSP to forward packets from PE 1 to PE 2.

   [P] static-lsp transit pe1-pe2 in-label 201 nexthop 10.2.2.1 out-label 202
   

   # Configure a static LSP to forward packets from PE 2 to PE 1.

   [P] static-lsp transit pe2-pe1 in-label 102 nexthop 10.1.1.1 out-label 101
   

4. Configure PE 2:

   # Configure an LSR ID.

   <PE2> system-view
   [PE2] interface loopback 0
   [PE2-LoopBack0] ip address 192.3.3.3 32
   [PE2-LoopBack0] quit
   [PE2] mpls lsr-id 192.3.3.3
   

   # Enable L2VPN.

   [PE2] l2vpn enable
   

   # Configure VLAN-interface 30 (the interface connected to P), and enable MPLS on the interface.

   [PE2] interface vlan-interface 30
   [PE2-Vlan-interface30] ip address 10.2.2.1 24
   [PE2-Vlan-interface30] mpls enable
   [PE2-Vlan-interface30] quit
   

   # Create service instance 10 on Ten-GigabitEthernet 1/0/1 to match packets that have an outer VLAN ID of 10.

   [PE2] interface ten-gigabitethernet1/0/1
   [PE2-Ten-GigabitEthernet1/0/1] service-instance 10
   [PE2-Ten-GigabitEthernet1/0/1-srv10] encapsulation s-vid 10
   [PE2-Ten-GigabitEthernet1/0/1-srv10] quit
   [PE2-Ten-GigabitEthernet1/0/1] quit
   

   # Create a cross-connect group named ccc, create a remote CCC connection that has incoming label 202, outgoing label 102, and next hop 10.2.2.2, and bind service instance 10 on Ten-GigabitEthernet 1/0/1 to the CCC connection.

   [PE2] xconnect-group ccc
   [PE2-xcg-ccc] connection ccc
   [PE2-xcg-ccc-ccc] ccc in-label 202 out-label 102 nexthop 10.2.2.2
   [PE2-xcg-ccc-ccc] ac interface Ten-GigabitEthernet 1/0/1 service-instance 10
   [PE2-xcg-ccc-ccc] quit
   [PE2-xcg-ccc] quit
   

5. Configure CE 2.

   <CE2> system-view
   [CE2] interface ten-gigabitethernet 1/0/1
   [CE2-Ten-GigabitEthernet1/0/1] port link-type trunk
   [CE2-Ten-GigabitEthernet1/0/1] port trunk permit vlan 10
   [CE2-Ten-GigabitEthernet1/0/1] quit
   

# Display L2VPN PW information on PE 1. The output shows that a remote CCC connection (identified by PW ID/Rmt Site "-" and Proto Static) has been established.

[PE1] display l2vpn pw
