Configuration considerations

Because a local CCC connection is bidirectional, one local CCC connection is enough for CE 1 and CE

2 to communicate with each other.

Configuration procedure

1. On CE 1, configure the link protocol type as PPP on Serial 2/0 (the interface connected to the PE),

and configure an IP address for the interface.

<Sysname> system-view

[Sysname] sysname CE1

[CE1] interface serial 2/0

[CE1-Serial2/0] link-protocol ppp

[CE1-Serial2/0] ip address 100.1.1.1 24

2. Configure the PE:

# Configure an LSR ID and enable MPLS globally.

<Sysname> system-view

[Sysname] sysname PE

[PE] interface loopback 0

[PE-LoopBack0] ip address 172.1.1.1 32

[PE-LoopBack0] quit

[PE] mpls lsr-id 172.1.1.1

[PE] mpls

[PE-mpls] quit

# Enable L2VPN and MPLS L2VPN.

[PE] l2vpn

[PE-l2vpn] mpls l2vpn

[PE-l2vpn] quit

# Configure the link protocol type of interface Serial 2/0 as PPP.

[PE] interface serial 2/0

[PE-Serial2/0] link-protocol ppp

[PE-Serial2/0] quit

# Configure the link protocol type of interface Serial 2/1 as PPP.
