Usage
Information
Loopback interfaces are up constantly and the BGP session may need one
interface constantly up to stabilize the session. The neighbor update-source
command is not necessary for directly connected internal BGP sessions.
Neighbors are sorted according to the source and destination ip addresses. If an
update-source ip address exists, then the source ip address determines the order in
which the neighbors are displayed.
