Collector is a BGP Link-State collector

Events() returns the events channel or an error if the collector has been stopped. The events channel is buffered, its size is configurable via CollectorConfig. The events channel should be read from in a loop. It will close only when Stop() is called.

Config() returns the configuration of the Collector.

AddNeighbor() initializes a new bgp-ls neighbor. An error is returned if the collector is stopped or the neighbor already exists.

DeleteNeighbor() shuts down and removes a neighbor from the collector. An error is returned if the collector is stopped or the neighbor does not exist.

Neighbors() returns the configuration of all neighbors.

Stop() stops the collector and all neighbors.

package main

	}

	for {
		event := <-eventsChan
		// all Event types can be found in event.go (EventNeighbor**)
