Enabling immediate reestablishment of direct EBGP
connections upon link failure
When the link to a directly-connected EBGP peer goes down, the router does not reestablish a session to
the peer until the hold time timer expires. This feature enables BGP to immediately recreate the session
in that situation. When this feature is disabled, route flapping does not affect EBGP session state.
