bridge-domain

Creates a bridge domain, which represents a switching or inter-connection domain for a wide range of service end-point types.

Syntax

bridge-domain bd-id [ p2mp | p2p ]

no bridge-domain bd-id [ p2mp | p2p ]

Command Default

No bridge domain is configured.

Parameters

bd-id: Specifies a unique numeric bridge-domain identifier. For supported values, see the Usage Guidelines.
p2mp: Specifies a multipoint service type. This is the default service type.
p2p: Specifies a point-to-point cross-connect service type.

Modes

Global configuration mode.

Usage Guidelines

The range of supported bridge-domain ID values varies with device:

For Extreme 8720, Extreme 8520, SLX 9250, and SLX 9150 devices - From 1 through 1024.
For Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices - From 1 through 4096.

(For Extreme 8820, SLX 9740, SLX 9640, and SLX 9540) VPLS performs any-to-any switching between Ethernet attachment circuits (ACs) and MPLS pseudowires (PWs). VLL performs one-to-one switching between Ethernet AC and MPLS PWs. Use the bridge-domain to specify the related configuration for both VPLS and VLL.

The no version of this command removes the bridge-domain configuration.

Examples

The following example shows how to configure bridge domain 1 and specifies a point-to-point cross-connect service for the domain.

device# configure terminal
device(config)# bridge-domain 1 p2p

The following example shows the error message that is displayed when the specified bridge-domain ID is out of range.

device# configure terminal
device(config)# bridge-domain 10000000
Error: syntax error: "10000000" is out of range.

The following example shows the error message that is displayed when the bridge-domain creation is not successful in the back-end.

device# configure terminal
device(config)# bridge-domain 110
Error: bridge-domain: connection instance creation failed.
