ONFIGURATION

a Configure a static LSP, with the in-label 100, incoming interface SERIAL0/0/0,

out-label 101, and the outgoing interface SERIAL1/0/0.

CAUTION:

1) The conditions for a CCC local connection to enter UP state:

The physical states of the two CE interfaces are in UP state.

The encapsulation type for the two CE interfaces is consistent and supported in
current MPLS L2VPN.

2) For a MPLS L2VPN of VLAN encapsulation type, the VLAN IDs for the two CE
interfaces can be inconsistent.

SVC Configuration

Example

Networking Requirement

Configure a remote SVC connection of FR encapsulation type between CE1 and
CE4.

For normal communication of CE1~CE4, you should match DCE/DTE in
configuration. Here on the path CE1-PE1-PE3-CE4, CE1 is DCE, PE1 is DTE, PE3 is
DCE and CE4 is DTE.
