Usage guidelines

Typically a BGP router does not send withdrawal messages of the default route prior to other routes to its peers. If the peer relationship is down, the default route cannot be withdrawn first. Traffic interruption might occur. After you execute this command, BGP sends withdrawal message of the default route prior to other routes when the peer relationship is down. Traffic can be immediately switched to a valid path to reduce the traffic interruption time.

Examples
