Abstract

A disclosed method of managing a provider edge (PE) router includes defining a neighbor specific prefix limit and a neighbor specific restart parameter applicable to a neighbor of the PE router. The neighbor may be a customer edge (CE) router connected to the PE router. A neighbor specific count of prefixes advertised by the CE router is monitored against the prefix limit. When a neighbor specific prefix limit violation occurs, the PE-to-CE connection is suspended for a duration determined at least in part by the restart parameter and then automatically resumed. The PE router may define an address family prefix limit and an address family restart parameter applicable to the CE router's address family. Violations of the address family prefix limit may result in temporary suspension of all connections between the PE router and the members of the address family.
