This is referred to as up convergence. Similarly, how fast the prefixes are withdrawn from the VPN sites after a failure in the network occurs to minimize the black holing of traffic is referred to as the down convergence. This session explains. in depth. various tunable variables that affect both the up convergence and down convergence in Multiprotocol Label Switching (MPLS) L3VPN networks.
