set protocols mpls ldp dual-stack transport-connection prefer-ipv4

The set protocols mpls ldp dual-stack transport-connection prefer-ipv4 command configures to instruct the router to prefer IPv4 for the transport connection when establishing LDP sessions in a dual-stack environment where both IPv4 and IPv6 are enabled.

The delete protocols mpls ldp dual-stack transport-connection command deletes the configuration.

Command Syntax

set protocols mpls ldp dual-stack transport-connection prefer-ipv4

delete protocols mpls ldp dual-stack transport-connection

Parameter

Null.

Usage Guidelines

By default, routers running MPLS with LDP in a dual-stack environment use IPv6 for the transport connection. However, in certain scenarios, such as network interoperability requirements or specific operational preferences, it may be desirable to explicitly specify IPv4 as the preferred transport protocol.

Example

• Configure to instruct the router to prefer IPv4 for the transport connection when establishing LDP sessions in a dual-stack environment where both IPv4 and IPv6 are enabled.
