connection by starting a path switch.
Requirements and Restrictions

- After the path switch is completed successfully, use the ZNRTP ROUTE
command to display the new route for the RTP connection.
- If a network failure occurs that causes an RTP connection to be
automatically switched to a backup (less desirable) route, use this command to
switch back to the primary route once that route becomes available
again.
- Data traffic continues to flow on the RTP connection while the path switch
is in progress.
- If the path switch fails, the RTP connection will continue to use its
existing route.
