ce

Function

The ce command creates a CE in an MPLS VPN instance and displays the MPLS-L2VPN-CE view.

The undo ce command deletes a CE from an MPLS L2VPN instance.

By default, no CE is configured in an MPLS VPN instance.

Format

ce ce-Name [ id ce-id [ range ce-range ] [ default-offset ce-offset ] ]

undo ce ce-Name

Parameters

Parameter	Description	Value
ce-Name	Specifies a CE name.	The value is a string of 1 to 20 case-sensitive characters, spaces not supported. The string can contain spaces if it is enclosed in double quotation marks (").
id ce-id	Specifies a CE ID. A CE ID uniquely identifies a CE in an MPLS VPN instance. It is recommended that CE IDs be numbered with consecutive numbers starting from 1.	The value is an integer ranging from 0 to 65534.
range ce-range	Specifies a CE range.	The value is an integer ranging from 1 to 65535. The default value is 10.
default-offset ce-offset	Specifies a CE offset, or the difference between the remote and local CE IDs.	The value is 0 or 1. The default value is 0.

Usage Guidelines

Usage Scenario

In a BGP VPWS scenario, after an MPLS L2VPN instance is configured, the ce command must be run to create a CE in the L2VPN instance. In the ce command, you can specify ce-name, ce-id, ce-range, and the maximum number of CE connections allowed.

Prerequisites

An RD has been configured using the route-distinguisher <route-distinguisher> command for the MPLS L2VPN instance.

Precautions

The relationships between ce-range and ce-offset in the ce command and ce-offset-id in the connection command are as follows:
If ce-offset is 0, ce-offset-id must be smaller than ce-range.
If ce-offset is 1, ce-offset-id must be smaller than or equivalent to ce-range and must not be 0.
The ce command can only be used to increase the ce-range value.

Example

# Create a CE in an MPLS L2VPN instance named vpn1.
