es.tid.bgp.bgp4.messages.BGP4Message

es.tid.bgp.bgp4.messages.BGP4Keepalive

All Implemented Interfaces:

BGP4Element

public class BGP4Keepalive
extends BGP4Message

BGP KeepAlive Message (RFC 4271).

From RFC 4271, Section 4.4

RFC 4271. KEEPALIVE Message Format BGP does not use any TCP-based, keep-alive mechanism to determine if peers are reachable. Instead, KEEPALIVE messages are exchanged between peers often enough not to cause the Hold Timer to expire. A reasonable maximum time between KEEPALIVE messages would be one third of the Hold Time interval. KEEPALIVE messages MUST NOT be sent more frequently than one per second. An implementation MAY adjust the rate at which it sends KEEPALIVE messages as a function of the Hold Time interval. If the negotiated Hold Time interval is zero, then periodic KEEPALIVE messages MUST NOT be sent. A KEEPALIVE message consists of only the message header and has a length of 19 octets.
