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.

Because the PE-CE 1 link type is FR, and the PE-CE 2 link type is ATM, you must configure the local CCC

connection on the PE to support IP interworking.

Configuration procedure

1. Configure CE 1:

# Configure the link protocol as frame relay on Serial 2/0, the interface connected to the PE.

<Sysname> system-view

[Sysname] sysname CE1

[CE1] interface serial 2/0

[CE1-Serial2/0] link-protocol fr

[CE1-Serial2/0] quit

# Create point-to-point subinterface Serial 2/0.1, and assign a frame relay virtual circuit and an

IP address to it.

[CE1] interface serial 2/0.1 p2p

[CE1-Serial2/0.1] fr dlci 100

[CE1-fr-dlci-Serial2/0.1-100] quit

[CE1-Serial2/0.1] ip address 100.1.1.1 24

[CE1-Serial2/0.1] quit

2. Configure the PE:

# Configure the 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
