peer virtual-link twamp-light test-session

Function

The peer virtual-link twamp-light test-session command configures TWAMP-Light for a virtual link.

The undo peer virtual-link twamp-light test-session command cancels the configuration.

By default, TWAMP Light is not configured for a virtual link.

Usage Guidelines

Usage Scenario

The delay of the BGP peer virtual link is detected through TWAMP Light. Therefore, a test session needs to be bound to the link. When binding the test session to the test session, ensure that the local and remote addresses of the session are the same as those of the BGP peer virtual link.

Prerequisites

A TWAMP Light IPv6 session has been configured, and the measurement service is to be started.
A virtual link across an L3 network has been constructed using the peer virtual-link command. Topology information is reported to the controller based on the virtual link for path computation.
